Feature summary
Applications
Description
The STC4054 is a constant current/constant voltage charger for single cell Li-Ion batteries. No external sense resistor or blocking diode is
Table 1. Pin description
| Pin N° | Symbol | Note |
|---|---|---|
| 1 | CHRG | Open Drain. This pin goes in low impedance when the STC4054 is in precharge orcharge mode |
| 2 | GND | Ground pin |
| 3 | BAT | This pin provides an accurate 4.2V output voltage and the charge current to the battery.Only 2µA reverse current can flow in to the device when in Shutdown mode |
| 4 | VCC | Input Supply voltage. The input range is from 4.25V to 6.5V. If VCC<VBAT+30mV thedevice enters Shutdown mode and the sinked IBAT is less than 2µA |
| 5 | PROG | Charge current program. Charge Current monitor and Shutdown pin |
