Datasheet Voltage Detector IC Series Free Delay Time Setting CMOS Voltage Detector IC Series BD52xx series BD53xx series General Description Key Specifications Rohm s BD52xx and BD53xx series are highly Detection voltage: 2.3V to 6.0V (Typ.) accurate, low current consumption Voltage Detector 0.1V steps ICs with a capacitor-controlled time delay. The line up High accuracy detection voltage: 1.0% includes BD52xx devices with N channel open drain Ultra-low current consumption: 0.95A (Typ.) output and BD53xx devices with CMOS output. The Package W(typ) x D(typ) x H(max) devices are available for specific detection voltages SSOP5: 2.90mm x 2.80mm x 1.25mm ranging from 2.3V to 6.0V in increments of 0.1V. Features VSOF5: 1.60mm x 1.60mm x 0.60mm Delay Time Controlled by external Capacitor Two output types (N channel open drain and CMOS Applications Circuits using microcontrollers or logic circuits that output) require a reset. Ultra-low current consumption Very small and low height package Package SSOP5 is similar to SOT-23-5(JEDEC) Typical Application Circuit VDD1 VDD1 VDD2 RL Micro RST BD53xx controller Micro BD52xx RST controller CT CT CL CL (Capacitor for (Capacitor for noise filtering) noise filtering) GND GND Open Drain Output type CMOS Output type BD52xx Series BD53xx Series Connection Diagram CT N.C.
