Datasheet Voltage Detector IC Series Counter Timer Built-in CMOS Voltage Detector IC BD45xxx series BD46xxx series Key Specifications General Description Detection voltage: 2.3V to 4.8V (Typ.) ROHMs BD45xxx and BD46xxx series are highly 0.1V steps accurate, low current consumption Voltage Detector ICs. High accuracy detection voltage: 1.0% Because the counter timer delay circuit is built into Ultra-low current consumption: 0.85A (Typ.) these series, an external capacitor for the delay time Operating temperature range: -40C to +105C setting is unnecessary. The lineup was established with Three internal, fixed delay time: 50ms low output types (Nch open drain and CMOS output) 100ms and detection voltages range from 2.3V to 4.8V in 200ms increments of 0.1V, so that the series may be selected Package according the application at hand. SSOP5 2.90mm x 2.80mm x 1.25mm Features Counter Timer Built-in Applications No delay time setting external capacitor required Circuits using microcontrollers or logic circuits that Ultra-low current consumption require a reset. Two output types (Nch open drain and CMOS output) Package SSOP5 is similar to SOT-23-5 (JEDEC) Typical Application Circuit VDD1 VDD2 VDD1 RL Micro Micro BD46xxx RST BD45xxx RST controller controller CL CL Noise-filtering Noise-filtering Capacitor Capacitor GND GND Open Drain Output Type CMOS Output Type BD45xxx series BD46xxx 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.
