The BD46E321G-M is a CMOS output type voltage detector designed for automotive applications, featuring a fixed delay of 100 milliseconds. It operates with a detection voltage of 3.2V and offers high accuracy with a typical detection voltage tolerance of ¬±1.0%. The device consumes ultra-low current, typically 0.85¬µA, making it suitable for power-sensitive applications. It is packaged in a compact SSOP5 format, measuring 2.90mm x 2.80mm x 1.25mm, and is AEC-Q100 qualified, ensuring reliability in automotive environments. The operating temperature range is from -40¬8C to +105¬8C, which is essential for automotive applications. This product is ideal for circuits that require a reset function, such as microcontrollers in car navigation systems, audio systems, and meter panels.
ROHM’s BD45Exxxx-M and BD46Exxxx-M series are highly accurate, low current consumption Voltage Detector IC series. Because the counter timer delay circuit is built into those series, an external capacitor for the delay time setting is unnecessary. The lineup was established with two output types (Nch open drain output) and detection voltages range from 2.3Vto 4.8V in increments of 0.1V, so that the series may be selected according to application.
