Datasheet Voltage Detector IC Series for Automotive Counter Timer Built-in CMOS Voltage Detector IC BD45Exxxx-M series BD46Exxxx-M series ●General Description 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 and CMOS output) and detection voltages range from 2.3V to 4.8V in increments of 0.1V, so that the series may be selected according to application. ●Features  Counter Timer Built-in  No delay time setting capacitor required  Ultra-low current consumption  Two output types (Nch open drain and CMOS output)  Package SSOP5 is similar to SOT-23-5 (JEDEC)  AEC-Q100 Qualified ●Key Specifications  Detection voltage: 2.3V to 4.8V (Typ.)  High accuracy detection voltage:  Ultra-low current consumption:  Operating temperature range:  Three internal, fixed delay time: 0.1V steps ±1.0% 0.85µA (Typ.) -40°C to +105°C 50ms 100ms 200ms ●Package SSOP5 2.90mm x 2.80mm x 1.25mm ●Applications Circuits using microcontrollers or logic circuits that require a reset for automotive applications (car navigation, car audio, meter panel, exterior lamp etc.) ●Typical Application Circuit VDD1 VDD2 BD45Exxxx-M RL Micro RST controller CL (Noise-filtering Capacitor) (Open Drain Output Type) BD45Exxxx-M series ●Connection Diagram SSOP5 VDD VOUT GND TOP VIEW Marking Lot.
