STM6600CS25DM6F from STMicroelectronics, in a TDFN-12(2x3). 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 | VCC | power_in | Power supply input monitored during startup and normal operation; operating voltage range 1.6 V to 5.5 V; decoupling 0.1 µF capacitor required as close as possible to device. |
| 2 | SR | input | Smart Reset™ button input with factory-trimmed voltage threshold and ±8 kV HBM ESD protection; active low input connected to GND through momentary push-button; 100 kΩ optional internal pull-up resistor. |
| 3 | VREF | power_out | Precise 1.5 V voltage reference output with 1% accuracy; available after tREC expires; mandatory 1 µF external capacitor must be connected. |
| 4 | PSHOLD | input | Power supply hold input with factory-trimmed voltage detector threshold; driven high during startup to confirm proper power-up or low during operation to trigger shutdown; internal pull-down resistor during startup. |
| 5 | CSRD | input | Smart Reset™ delay time capacitive input; external capacitor to ground determines additional delay tSRD at approximately 10 s/µF; leave open if not used. |
| 6 | PB | input | Power-on push-button input with factory-trimmed voltage threshold and ±8 kV HBM ESD protection; active low input with internal 100 kΩ pull-up resistor; connected to GND through momentary push-button. |
| 7 | VCCLO | output | High threshold detection output; active low open drain pulled low when VCC below VTH+ during startup or when undervoltage detected during operation; requires 10 kΩ pull-up resistor; floating in standby mode. |
| 8 | PBOUT | output | Push-button status output; active low open drain reflecting PB input state after tDEBOUNCE debounce period; stays low minimum tINT_Min if PB held; requires 10 kΩ pull-up resistor. |
| 9 | EN | output | Enable output (active high for STM6600CS25DM6F); push-pull output asserted after valid power-up event and PSHOLD confirmation; deasserted by button release before PSHOLD confirmation, PSHOLD forced low, undervoltage detected, or long push (>tDEBOUNCE + tSRD). |
| 10 | RST | output | Reset output; active low open drain pulled low for tREC minimum 240 ms during power-up after PB falling edge and tDEBOUNCE; requires 10 kΩ pull-up resistor. |
| 11 | INT | output | Interrupt output; active low open drain asserted when PB pressed for tDEBOUNCE or more during normal operation or when VCC falls below VTH- threshold; held high during power-up; minimum pulse width tINT_Min; requires 10 kΩ pull-up resistor. |
| 12 | GND | power_in | Ground; device reference potential and application circuit return. |
| 13 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
