SRC0
SRC0 is Smart push-button on/off controller manufactured by STMicroelectronics.
Features
- Operating voltage 1.6 V to 5.5 V
- Low standby current of 0.6 µA
- Adjustable Smart Reset™ assertion delay time driven by external CSRD
- Power-up duration determined primarily by push-button press
- Debounced PB and SR inputs
- PB and SR ESD inputs withstand voltage up to ±15 k V (air discharge) ±8 k V (contact discharge)
- Active high or active low enable output option (EN or EN) provides control of MOSFET, DCDC converter, regulator, etc.
- Secure startup, interrupt, Smart Reset™ or power-down driven by push-button
- Precise 1.5 V voltage reference with 1% accuracy Table 1. Device summary

CSRD PB / SR EN or EN
Startup process
SRC0 open drain(1)
3 push-pull open drain(1)
PB must be held low until the PSHOLD(2) confirmation
1. External pull-up resistor needs to be connected to open drain outputs.
2. For a successful startup, the PSHOLD (Power Supply Hold) needs to be pulled high within specific time, t ON_BLANK.
