The SGM850 has an exact windowed voltage supervisor with 1.4% accuracy for both over-voltage (VIT + OV) and under-voltage (VIT - UV) thresholds over the temperature from -40℃ to +125℃. It also possesses accurate hysteresis on both thresholds for some systems that need small tolerance. The device output (nRESET) delay can either be determined by factory default settings, or be determined by the external capacitor at CRST pin.
The SGM850 has an adjustable watchdog timer and a special watchdog output (nWDO). The nWDO can be used to locate the fault causes. The watchdog timeout period can either be determined by factory default settings, or be determined by the external capacitor at CWD pin. The watchdog function can be closed through SETx (x = 0, 1) pin to prevent some specific watchdog timeout events.
The SGM850 is available in a Green TDFN-3×3-10AL package.
