Datasheet Voltage Detector IC Series Standard CMOS Voltage Detector IC BD48xxx series BD49xxx series General Description Key Specifications ROHMs BD48xxx and BD49xxx series are highly Detection voltage: 2.3V to 6.0V (Typ.), accurate, low-current Voltage Detector IC series. The 0.1V steps family includes BD48xxx devices with N-channel open High accuracy detection voltage: 1.0% drain output and BD49xxx devices with CMOS output. Ultra-low current consumption: 0.9A (Typ.) The devices are available for specific detection voltages Operating temperature range: -40C to +105C ranging from 2.3V to 6.0V in increments of 0.1V. Package SSOP5: 2.90mm x 2.80mm x 1.25mm Features High accuracy detection SSOP3: 2.92mm x 2.80mm x 1.25mm Ultra-low current consumption Two output types (Nch open drain and CMOS output) VSOF5: 1.60 mm x 1.60mm x 0.60mm Wide Operating temperature range Very small and low height package Applications Package SSOP5 is similar to SOT-23-5 (JEDEC) Circuits using microcontrollers or logic circuits that Package SSOP3 is similar to SOT-23-3 (JEDEC) require a reset.
