+## Overview
23
+
24
+LY6367 is a fully integrated power management chip for Bluetooth charging cases, integrating lithium battery charging management, synchronous boost converter, battery power management, and protection function modules.
25
+
26
+LY6367 uses a proprietary boost control circuit structure that perfectly supports PCB trace inductance, greatly reducing solution size and cost.
27
+
28
+LY6367 offers two charging current versions: 180mA and 400mA, with a maximum discharge current of 600mA. It supports MCU direct reading of charging, fully charged, discharging, and standby status.
29
+
30
+## Applications
31
+
32
+- Bluetooth earphone charging cases
33
+
34
+- Power banks
35
+
36

- Operation: Normally open (OFF) at rest. When subject to impact or sufficient acceleration/centrifugal force, the internal contact momentarily closes (ON) and the electrical state changes; when the force is removed the switch returns to open (OFF).
123 125
- No orientation required: Omnidirectional — it can trigger from any angle.
124 126
- Sealed version: Models with a trailing "P" are fully sealed for waterproof and dustproof applications.
