STM6601BS2BDM6F

STMicroelectronics · Supervisor And Reset ICs · TDFN-12(2x3)

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).
