Features
Overview
•
•
•
•
•
The Charger Detect module has two main functions:
• Control the device operating state (Power-off or normal operation)
• Detect when a charger is connected/disconnected
Figure 22-1
Figure 22-1. Charger Detect block diagram.
Operates directly from VFET supply
Detects when a charger is connected or disconnected by monitoring the BATT pin
Controls the operation state of the device by automatically enable/disable the internal Voltage
Regulator
Automatically disabled when Discharge FET is ON.
Interrupt wake-up from all sleep modes
