Datasheet 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 .

Datasheet 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: ●Typical Application Circuit VDD1 RL BD45xxx RST Micro controller BD46xxx RST Micro controller VDD2 VDD1 CL (Noise-filtering Capacitor) CL GND (Noise-filtering Capacitor) GND (Open Drain Output Type) BD45xxx series ●Connection Diagram SSOP5 VDD VOUT PIN No. 1 2 TOP VIEW (CMOS Output Type) BD46xxx series ●Pin Descriptions Symbol ER SUB GND VOUT VDD Function Manual Reset Substrate * GND Reset Output Power Supply Voltage 3 Lot.
