STM6601BS2BDM6F 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 operating at 1.6 V to 5.5 V, requires 0.1 µF decoupling capacitor placed as close to device as possible. |
| 2 | SR | input | Smart Reset™ button input with factory-trimmed voltage detector and ±8 kV HBM ESD protection, active low with optional internal 100 kΩ pull-up resistor. |
| 3 | VREF | power_in | Precise 1.5 V voltage reference output with 1% accuracy, requires mandatory 1 µF capacitor, output enabled after RST deasserts and disabled in standby mode. |
| 4 | PSHOLD | input | Power-supply hold input with factory-trimmed voltage detector and internal pull-down during startup, confirms correct power-up or initiates shutdown. |
| 5 | CSRD | passive | Smart Reset™ delay time capacitor input charged with ISRD current to set additional delay tSRD, leave pin open if capacitor not used. |
| 6 | PB | input | Push-button power-on input with factory-trimmed voltage detector and ±8 kV HBM ESD protection, active low with internal 100 kΩ pull-up resistor and switch to ground. |
| 7 | VCCLO | output | Active low open-drain output indicating VCC above VTH+ threshold or undervoltage detection, requires pull-up resistor, floating in standby mode. |
| 8 | PBOUT | output | Active low open-drain output indicating PB push-button input status with tDEBOUNCE response time, requires pull-up resistor. |
| 9 | EN | output | Push-pull enable output (active low variant) controlling system power, asserted low after valid turn-on confirmation and released high on power-down conditions. |
| 10 | RST | output | Active low open-drain reset output asserted for tREC (240 ms minimum) during startup or after long push detection, requires pull-up resistor. |
| 11 | INT | output | Active low open-drain interrupt output asserted for minimum tINT_Min during push-button interrupt or undervoltage detection in normal operation, requires pull-up resistor. |
| 12 | GND | power_in | Ground reference pin. |
| 13 | EP | passive | Exposed pad (from the footprint; not named in the datasheet pin table). |
