BD46232G-TR

Overview

The BD46232G-TR is a voltage detector manufactured by ROHM Semiconductor, designed for monitoring single-input supply voltages. It features a typical under-voltage detection threshold of 2.3 V with a precision of ±1%. The device operates within a reset active voltage range of 0.95 V to 10 V and supports a maximum power supply voltage of 10 V. It provides a fixed reset delay time of 200 ms and utilizes an open-drain output type. The component is housed in an SSOP-5 package and supports manual reset functionality. It lacks a watchdog timer and battery backup switch. The circuit current is specified at 0.80 μA (on) and 0.85 μA (off) at Vdet=4.8V, with a hysteresis voltage included in specifications.
