Voltage Detector IC Series
Counter Timer Built-in CMOS Voltage Detector IC
BD45xxx series BD46xxx series
●General Description ROHM’s BD45xxx and BD46xxx series are highly accurate, low current consumption Voltage Detector ICs. Because the counter timer delay circuit is built into these series, an external capacitor for the delay time setting is unnecessary. The lineup was established with low 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 the application at hand. ●Features Counter Timer Built-in No delay time setting external capacitor required Ultra-low current consumption Two output types (Nch open drain and CMOS output) Package SSOP5 is similar to SOT-23-5 (JEDEC) 2.3V to 4.8V (Typ.) 0.1V steps High accuracy detection voltage: ±1.0% Ultra-low current consumption: 0.85µA (Typ.) Operating temperature range: -40°C to +105°C Three internal, fixed delay time: 50ms 100ms 200ms ●Package SSOP5 2.90mm x 2.80mm x 1.25mm ●Applications Circuits using microcontrollers or logic circuits that require a reset. ●Key Specifications Detection voltage:
