          -TPS382x Voltage Monitor With Watchdog Timer

          -

          -The TPS382x family of supervisors provide circuit initialization and timing supervision, primarily for DSP and processor-based systems. 

          -

          -During power on, RESET asserts when the supply voltage VDD becomes greater than 1.1 V. Thereafter, the supply voltage supervisor monitors VDD and keeps RESET active low as long as VDD remains less than the threshold voltage, VIT−. An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset. 

          -

          -The delay time, td, starts after VDD has risen above the threshold voltage (VIT− + VHYS). When the supply voltage drops below the threshold voltage VIT−, the output becomes active (low) again. No external components are required. All the devices of this family have a fixed-sense threshold voltage, VIT–, set by an internal voltage divider. 

          -

          -The TPS382x family also offers watchdog time out options of 200 ms (TPS3820) and 1.6 s (TPS3823, TPS3824, and TPS3828).

          -

          -

          -TPS382x 系列监控器主要为 DSP 以及基于处理器的系统提供电路初始化和计时监控等功能。

          -

          -上电期间，RESET 会在电源电压 VDD 超出 1.1V 时置为有效。

          -

          -因此 VDD 保持在阈值电压 VIT− 以下，电源电压监控器就会监测 VDD 并将 RESET 保持为低电平有效。内部计时器将会延迟输出恢复至无效状态（高电平）的时间，以确保系统正常复位。延时时间 td 始于 VDD 上升至高于阈值电压 (VIT− + VHYS) 之后。当电源电压降到阈值电压 VIT− 以下时，输出再次变为有效状态（低电平）。无需外部组件。该系列中的所有器件均具有一个通过内部分压器设定的固定检测阈值电压 VIT–。TPS382x 系列还提供 200ms (TPS3820) 和 1.6s（TPS3823、TPS3824 和 TPS3828）的看门狗超时选项。

          +Applications

          +

          +- `DIY an output adjustable vehicle power supply`, only need access to your 12V power input, the output voltage can (14-35V)  continuously adjust, but the output voltage can not be lower than the input voltage.

          +- `Universal on-vehicle laptop power supply`. Input connector on your 12V power supply, the output voltage is adjusted to your laptop to work.

          +- `Boost charger`, you can use the 12V power supply is higher than 12V battery charging, for example, 24V battery.

          +- `Power for your electronic devices`, as long as the voltage and current of the voltage regulator to your needs can not exceed the rated current is working properly.

          +- `Primary front level system power supply`, when you do a project at the time of 10-18V input when the system board and you need to supply 24V and about its great power, with ordinary DC-DC module power is too small , then you choose this module we will be your best choice, do not debug directly on the machine to work, easy to do and efficient power boost.

          +### TPS382x

          +

          +TPS382x Voltage Monitor With Watchdog Timer

          +

          +The TPS382x family of supervisors provide circuit initialization and timing supervision, primarily for DSP and processor-based systems. 

          +

          +During power on, RESET asserts when the supply voltage VDD becomes greater than 1.1 V. Thereafter, the supply voltage supervisor monitors VDD and keeps RESET active low as long as VDD remains less than the threshold voltage, VIT−. An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset. 

          +

          +The delay time, td, starts after VDD has risen above the threshold voltage (VIT− + VHYS). When the supply voltage drops below the threshold voltage VIT−, the output becomes active (low) again. No external components are required. All the devices of this family have a fixed-sense threshold voltage, VIT–, set by an internal voltage divider. 

          +

          +The TPS382x family also offers watchdog time out options of 200 ms (TPS3820) and 1.6 s (TPS3823, TPS3824, and TPS3828).

          +

          +

          +TPS382x 系列监控器主要为 DSP 以及基于处理器的系统提供电路初始化和计时监控等功能。

          +

          +上电期间，RESET 会在电源电压 VDD 超出 1.1V 时置为有效。

          +

          +因此 VDD 保持在阈值电压 VIT− 以下，电源电压监控器就会监测 VDD 并将 RESET 保持为低电平有效。内部计时器将会延迟输出恢复至无效状态（高电平）的时间，以确保系统正常复位。延时时间 td 始于 VDD 上升至高于阈值电压 (VIT− + VHYS) 之后。当电源电压降到阈值电压 VIT− 以下时，输出再次变为有效状态（低电平）。无需外部组件。该系列中的所有器件均具有一个通过内部分压器设定的固定检测阈值电压 VIT–。TPS382x 系列还提供 200ms (TPS3820) 和 1.6s（TPS3823、TPS3824 和 TPS3828）的看门狗超时选项。

45		-### TPS382x
46		-
47		-TPS382x Voltage Monitor With Watchdog Timer
48		-
49		-The TPS382x family of supervisors provide circuit initialization and timing supervision, primarily for DSP and processor-based systems.
50		-
51		-During power on, RESET asserts when the supply voltage VDD becomes greater than 1.1 V. Thereafter, the supply voltage supervisor monitors VDD and keeps RESET active low as long as VDD remains less than the threshold voltage, VIT−. An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset.
52		-
53		-The delay time, td, starts after VDD has risen above the threshold voltage (VIT− + VHYS). When the supply voltage drops below the threshold voltage VIT−, the output becomes active (low) again. No external components are required. All the devices of this family have a fixed-sense threshold voltage, VIT–, set by an internal voltage divider.
54		-
55		-The TPS382x family also offers watchdog time out options of 200 ms (TPS3820) and 1.6 s (TPS3823, TPS3824, and TPS3828).
56		-
57		-
58		-TPS382x 系列监控器主要为 DSP 以及基于处理器的系统提供电路初始化和计时监控等功能。
59		-
60		-上电期间，RESET 会在电源电压 VDD 超出 1.1V 时置为有效。
61		-
62		-因此 VDD 保持在阈值电压 VIT− 以下，电源电压监控器就会监测 VDD 并将 RESET 保持为低电平有效。内部计时器将会延迟输出恢复至无效状态（高电平）的时间，以确保系统正常复位。延时时间 td 始于 VDD 上升至高于阈值电压 (VIT− + VHYS) 之后。当电源电压降到阈值电压 VIT− 以下时，输出再次变为有效状态（低电平）。无需外部组件。该系列中的所有器件均具有一个通过内部分压器设定的固定检测阈值电压 VIT–。TPS382x 系列还提供 200ms (TPS3820) 和 1.6s（TPS3823、TPS3824 和 TPS3828）的看门狗超时选项。

	45	+### TPS382x
	46	+
	47	+TPS382x Voltage Monitor With Watchdog Timer
	48	+
	49	+The TPS382x family of supervisors provide circuit initialization and timing supervision, primarily for DSP and processor-based systems.
	50	+
	51	+During power on, RESET asserts when the supply voltage VDD becomes greater than 1.1 V. Thereafter, the supply voltage supervisor monitors VDD and keeps RESET active low as long as VDD remains less than the threshold voltage, VIT−. An internal timer delays the return of the output to the inactive state (high) to ensure proper system reset.
	52	+
	53	+The delay time, td, starts after VDD has risen above the threshold voltage (VIT− + VHYS). When the supply voltage drops below the threshold voltage VIT−, the output becomes active (low) again. No external components are required. All the devices of this family have a fixed-sense threshold voltage, VIT–, set by an internal voltage divider.
	54	+
	55	+The TPS382x family also offers watchdog time out options of 200 ms (TPS3820) and 1.6 s (TPS3823, TPS3824, and TPS3828).
	56	+
	57	+
	58	+TPS382x 系列监控器主要为 DSP 以及基于处理器的系统提供电路初始化和计时监控等功能。
	59	+
	60	+上电期间，RESET 会在电源电压 VDD 超出 1.1V 时置为有效。
	61	+
	62	+因此 VDD 保持在阈值电压 VIT− 以下，电源电压监控器就会监测 VDD 并将 RESET 保持为低电平有效。内部计时器将会延迟输出恢复至无效状态（高电平）的时间，以确保系统正常复位。延时时间 td 始于 VDD 上升至高于阈值电压 (VIT− + VHYS) 之后。当电源电压降到阈值电压 VIT− 以下时，输出再次变为有效状态（低电平）。无需外部组件。该系列中的所有器件均具有一个通过内部分压器设定的固定检测阈值电压 VIT–。TPS382x 系列还提供 200ms (TPS3820) 和 1.6s（TPS3823、TPS3824 和 TPS3828）的看门狗超时选项。
