21
+The AP22652, AP22653, AP22652A, and AP22653A are singlechannel, precision-adjustable, current-limited switches optimized for applications that require precision current limiting, or to provide up to 2.1A of continuous load current during heavy loads/short circuits.
22
+
23
+These devices offer a programmable current-limit threshold between 125mA and 2665mA (typ) via an external resistor. Current-limit accuracy ±10% can be achieved at high current-limit settings. The rise and fall times are controlled to minimize current surges during turn on/off.

+ID_SD and ID_SC PINS:

14
+These pins are reserved for HAT ID EEPROM.
15
+
16
+At boot time this I2C interface will be interrogated to look for an EEPROM that identifes the attached board and allows automagic setup of the GPIOs (and optionally, Linux drivers).
17

18
+DO NOT USE these pins for anything other than attaching an I2C ID EEPROM. Leave unconnected if ID EEPROM not required.
