MCP73831T-2ACI/OT SMD IC (Original)

Description

1. Charge Status Output (STAT)
STAT is output for connection to an LED for charge status indication. Alternatively, a pull-up resistor can be applied for interfacing to a host microcontroller. STAT is a tri-state logic output on the MCP73831 and an open-drain output on the MCP73832.

2. Battery Management 0V Reference (VSS)
Connect to negative terminal of battery and input supply.

3. Battery Charge Control Output (VBAT)
Connect to the positive terminal of the battery. The drain terminal of internal P-channel MOSFET pass transistor. Bypass to VSS with a minimum of 4.7 µF to ensure loop stability when the battery is disconnected.

4. Battery Management Input Supply (VDD)
A supply voltage of [VREG (typical) + 0.3V] to 6V is recommended. Bypass to VSS with a minimum of 4.7 µF.

5. Current Regulation Set (PROG)
Preconditioning, fast charge and termination currents are scaled by placing a resistor from PROG to VSS. The charge management controller can be disabled by allowing the PROG input to float.
