The SGM855 is a nano-power system timer which only consumes 40nA (TYP) quiescent current. It has a programmable watchdog to interrupt the power MOSFET with the DRV pin. Hence, it is suitable for power gating in duty-cycled or battery-powered applications. Due to the power saving feature of SGM855, smaller battery can be adopted under power collection system or wireless sensor applications. The SGM855 can program the timer interval from 100ms to 8200s through the resistor placed between the DELAY/M_DRV pin and GND. Besides, the user can choose the timer to operate in timer mode or one-shot mode by the EN/ONE_SHOT pin.
The SGM855 is available a Green SOT-23-6 Package.
