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

STM6601DS2BDM6F 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 voltage 1.6 V to 5.5 V, requires 0.1 µF decoupling capacitor close to device.
2 SR input Smart Reset™ button input, active low with factory-trimmed threshold and ±8 kV HBM ESD protection; internal optional 100 kΩ pull-up resistor.
3 VREF power_out Precise 1.5 V voltage reference output with 1% accuracy, requires mandatory 1 µF capacitor to ground, disabled in standby mode.
4 PSHOLD input Power supply hold confirmation input with factory-trimmed threshold and internal pull-down resistor during startup; used to confirm power-up or initiate shutdown.
5 CSRD input Adjustable Smart Reset™ delay time input where external capacitor to ground determines delay time, capacitor charged with ISRD current.
6 PB input Power-ON push-button input, active low with factory-trimmed threshold and ±8 kV HBM ESD protection; internal 100 kΩ pull-up resistor connected.
7 VCCLO output High threshold comparator output (VTH+ detection), active low open drain, pulls low when VCC below VTH+ during power-up or during undervoltage.
8 PBOUT output Push-button input state indicator, active low open drain, remains low during debounce period and for minimum tINT_Min when PB is pressed.
9 EN output Inverted enable output (active low), push-pull type, asserts low after valid power-up confirmation, releases high on power-down conditions or long push.
10 RST output Reset output, active low open drain, asserts low for tREC during startup or after long push detection (depending on device option).
11 INT output Interrupt output, active low open drain, driven low on undervoltage or push-button press during normal operation with minimum tINT_Min assertion.
12 GND power_in Ground connection for power supply return and signal reference.
13 EP passive Exposed pad (from the footprint; not named in the datasheet pin table).
