TP4584B

TPOWER · Battery Management · ESOP8

TP4584B from TPOWER, in a ESOP8. 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 VDD power_in Charging input supply, recommended 4.5 V to 5.5 V (5 V typical), with an input overvoltage protection threshold of 6 V.
2 LED1 output Battery-level indicator LED driver (about 1.4 mA at VBAT=4 V); it flashes at 1 Hz while charging the current level, and at 2 Hz as a fast-flash low-battery warning when BAT falls below 3.05 V.
3 LED2 output Battery-level indicator LED driver (about 1.4 mA at VBAT=4 V) that shows charge and discharge state together with LED1 and LED3.
4 LED3 output Battery-level indicator LED driver (about 1.4 mA at VBAT=4 V) that shows charge and discharge state together with LED1 and LED2.
5 SWT input Push-button input: a single click (longer than 50 ms) turns the boost output on and shows battery level, and a double click within 500 ms turns it off; it has an internal pull-up of about 30 uA at VBAT=3.7 V.
6 BAT bidirectional Lithium-ion battery positive terminal used for linear charging (250 mA constant current, 4.2 V float) and as the boost discharge input, with BAT undervoltage lockout at 3.15 V rising.
7 SW passive Boost converter power switch node, which must connect to inductor L1 with a short, wide trace kept close to the BAT capacitor.
8 OUT power_out Boost regulated output (5 V nominal, 4.8 V to 5.2 V at 0.5 A load) with output overvoltage protection at 5.25 V and an output current limit of 500 mA maximum.
9 GND passive Exposed pad (from the footprint; not named in the datasheet pin table).
