HE5080E from HEERMICR, in a ESOP-8. 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 | VIN | power_in | 5 V USB or adapter input supply; recommended VDD is 3.44 V to 7.0 V with an absolute maximum of -0.3 V to 8.0 V, and a 1 uF ceramic capacitor should be placed at this pin. |
| 2 | AGND | power_in | Digital ground for the control circuitry. |
| 3 | LX | input | Drain of the internal power MOSFET, connected to the power inductor and Schottky diode, with a voltage rating of -0.3 V to 20 V. |
| 4 | VBS | power_out | Boost output that connects to the boost output and filter capacitors; the pin is rated -0.3 V to 10 V. |
| 5 | BAT | power_out | Charge output to the two-cell series Li-ion battery and a filter capacitor, with a standard float voltage of 8.40 V (8.35 V to 8.425 V) and a rating of -0.3 V to 10 V. |
| 6 | ICHG | input | Charge-current programming pin; a resistor from this pin to ground sets the constant charge current via I_CC = 6800 / R_CS, with a clamp voltage of 1 V in constant-current mode. |
| 7 | VSEN | input | Input-voltage sense and shutdown pin: charge current is reduced when VSEN falls to or below 1.2 V, and charging is shut down when VSEN is below 0.4 V. |
| 8 | STAT | output | Charge status output with an internal open-drain driver for an external indicator LED and current-limiting resistor; the LED stays on while charging and blinks at 1.3 Hz on fault conditions. |
| 9 | PGND | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
