BQ24314ADSGT

Texas Instruments · Battery Management · WSON-8-EP(2x2)

BQ24314ADSGT from Texas Instruments, in a WSON-8-EP(2x2). Pinout and pin descriptions extracted from the manufacturer datasheet (extract_pins, cross-checked by a second model); symbol, footprint, and 3D from KiCad-official CAD.

Pinout

Pin Name Type Function
1 IN input Input power connection to the external DC supply, with a 1 µF ceramic capacitor (minimum) to VSS; recommended input voltage range is 3 V to 30 V and the absolute maximum is 30 V.
2 VSS power_in Ground terminal, which must be connected to ground at all times.
3 NC unconnected Internal test-circuit pin that must have no external connection for normal operation.
4 FAULT output Active-low open-drain status output that is driven low on input overvoltage, input overcurrent, battery overvoltage or thermal shutdown, with a maximum sink current of 15 mA.
5 CE input Active-low chip enable input that turns the input FET off when driven high, and is internally pulled down so it can be left floating.
6 VBAT power_in Battery voltage sense input, connected to the pack positive terminal through a resistor, with an absolute maximum of 7 V with respect to VSS.
7 ILIM bidirectional Input overcurrent threshold programming pin, connected to VSS through a resistor RILIM between 15 kΩ and 90 kΩ, where IOCP = 25 ÷ RILIM (A, kΩ).
8 OUT output Output terminal to the charging system, with a 1 µF ceramic capacitor (minimum) to VSS; recommended output current is 1.5 A and the absolute maximum is 2 A.
9 PAD passive Exposed pad (from the footprint; not named in the datasheet pin table).
