The HG809RM3/TR SOT-23-3 Monitors & Reset Circuits ROHS manufactured by HGSEMI is a precision reset voltage detector. It is a three-pin SOT-23 package and features a wide detection voltage range, lock-up detection function, low power consumption, and internal hysteresis voltage. In addition, the reset voltage is typically monitored by the HG809RM3/TR which activate the RESET signal when the monitored voltage drops below a predetermined voltage threshold with a hysteresis value. This reset voltage detector is suitable for various applications such as power-on/off, system restart, overclock and overvoltage protection.
