STM1001 Reset circuit is a low power reset circuit with precision monitoring of 3V, 3.3V and 5V supply voltages, open drain RST output, 30ms or 140ms reset pulse width(min), low supply current - 6μA(typ), guaranteed RST assertion down to VCC= 1.0V and –40 °C to 85 °C operating temperature(industrial grade).
The STM1001 is a low-power supervisory device designed for microprocessor reset circuits. It monitors supply voltages (3 V, 3.3 V, and 5 V) and asserts an active-low reset signal whenever the voltage drops below a preset threshold. The device ensures the reset signal remains active for a minimum period of time (30 ms or 140 ms) after the voltage rises above the threshold.
