Datasheet Voltage Detector IC Series for Automotive Counter Timer Built-in CMOS Voltage Detector IC BD45Exxxx-M series BD46Exxxx-M series Key Specifications General Description Detection voltage: 2.3V to 4.8V (Typ.) ROHMs BD45Exxxx-M and BD46Exxxx-M series are 0.1V steps highly accurate, low current consumption Voltage High accuracy detection voltage: 1.0% Detector IC series. Because the counter timer delay Ultra-low current consumption: 0.85A (Typ.) circuit is built into those series, an external capacitor for Operating temperature range: -40C to +105C the delay time setting is unnecessary. The lineup was Three internal, fixed delay time: 50ms established with two output types (Nch open drain and 100ms CMOS output) and detection voltages range from 2.3V 200ms to 4.8V in increments of 0.1V, so that the series may be Package selected according to application. SSOP5 2.90mm x 2.80mm x 1.25mm Features Counter Timer Built-in No delay time setting capacitor required Applications Ultra-low current consumption Circuits using microcontrollers or logic circuits that Two output types (Nch open drain and CMOS output) require a reset for automotive applications (car Package SSOP5 is similar to SOT-23-5 (JEDEC) navigation, car audio, meter panel, exterior lamp etc.) AEC-Q100 Qualified Typical Application Circuit VDD1 VDD1 VDD2 RL Micro BD46Exxxx-M RST Micro controller BD45Exxxx-M RST controller CL CL Noise-filtering Noise-filtering Capacitor Capacitor GND GND CMOS Output Type Open Drain Output Type BD46Exxxx-M series BD45Exxxx-M series Connection Diagram Pin Descriptions SSOP5 VDD VOUT PIN No. Symbol Function 1 ER Manual Reset 2 SUB Substrate * 3 GND GND TOP VIEW 4 VOUT Reset Output Lot.
