1. Overview and Functionality

️· Device: SLG7NT128V - 1Hz Interrupt Generator
️· Type: Supervisor System, Oscillator
️· Function: Generates a 1Hz interrupt signal. It's controlled by three inputs.
️· Key Features:
- Voltage Monitoring: SENSE pin (Pin 4) monitors voltage. If it drops below 2.8V, the oscillator disables, and SMC_INICK goes LOW.
- Manual Reset: MBL_PWRGD_MR_N (Pin 3) provides a manual reset function for SMC_RST_N.
- Oscillator Disable: NMI_GATE (Pin 2) disables the oscillator.
- 20ms Supervisor Delay: After voltage is detected on SENSE pin (4), SMC_RST_N is set to HIGH with 20 ms delay.
️· Applications: Suitable for consumer market applications. Not intended for critical life-support systems.
