SRC0CS25D

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

SRC0CS25D from STMicroelectronics, in a DFN-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	VCC is the power supply input, monitored during startup and normal operation, and should be decoupled to ground with a 0.1 µF capacitor placed as close to the device as possible.
2	SR	input	Smart Reset button input with a factory-trimmed voltage detector and ±8 kV HBM ESD protection; it is usually connected to GND through a push-button, must not be grounded permanently, and is monitored for a falling edge after power-up.
3	VREF	power_out	Precise 1.5 V voltage reference specified with 1% accuracy, which requires a mandatory capacitor on the output even when unused (1 µF recommended).
4	PSHOLD	input	Input with a factory-trimmed voltage detector used to confirm power-up or initiate shutdown, with an internal pull-down during startup, where forcing it low during normal operation deasserts the enable output.
5	CSRD	passive	Smart Reset delay time input where a capacitor to ground sets the additional delay tSRD, and the pin should be left open if no capacitor is used.
6	PB	input	Power ON push-button input with a factory-trimmed voltage detector and ±8 kV HBM ESD protection, which must be switched to GND and has an internal 100 kΩ pull-up resistor.
7	VCCLO	output	High threshold (VTH+) detection output that is active-low and open drain by default, goes low when VCC is below VTH+ or during undervoltage, and requires a pull-up resistor (10 kΩ is sufficient in most applications).
8	PBOUT	output	Status output of the PB input that is active-low and open drain by default, stays low for at least tINT_Min after a valid press, ignores PB during undervoltage, and requires a pull-up resistor (10 kΩ is sufficient in most applications).
9	EN	output	Enable output asserted high after a valid turn-on is detected and confirmed, released low if the push-button is released before PSHOLD goes high, PSHOLD is driven low in normal operation, or an undervoltage or long push condition occurs as applicable; it is push-pull by default.
10	RST	output	Active-low open drain reset output that pulls low for tREC (240 ms min. per the product selector) during startup and, for the option asserting reset after long push, after a long push; it requires a pull-up resistor (10 kΩ is sufficient in most applications).
11	INT	output	Active-low open drain interrupt output driven low for at least tINT_Min when VCC falls below VTH- or when the push-button is held for tDEBOUNCE or more during normal operation, and it requires a pull-up resistor (10 kΩ is sufficient in most applications).
12	GND	power_in	Ground reference pin for the device.
13	EP	passive	Exposed pad (from the footprint; not named in the datasheet pin table).
