Additional Infomation About Product

Datasheet Voltage Detector IC Series Low Voltage Free Delay Time Setting CMOS Voltage Detector IC Series BU42xx series BU43xx series General Description Key Specifications ROHMs BU42xx and BU43xx series are CMOS Voltage Detection voltage: 0.9V to 4.8V (Typ.) Detector ICs with adjustable output delay. It is a 0.1V steps high-accuracy, low current consumption Voltage Detector High accuracy detection voltage: 1.0% IC series with a built-in delay circuit. The lineup was established with two output types (Nch open drain and Ultra-low current consumption: 0.55A (Typ.) CMOS output) and detection voltages range from 0.9V to Operating temperature range: -40C to +125C 4.8V in increments of 0.1V, so that the series may be Package selected according to application. SSOP5: 2.90mm x 2.80mm x 1.25mm Features Delay Time Controlled by external Capacitor SOP4: 2.00mm x 2.10mm x 0.95mm Two output types (Nch open drain and CMOS output) Ultra-low current consumption VSOF5: 1.60mm x 1.60mm x 0.60mm Wide operating temperature range Very small and low height package Applications Package SSOP5 and SOP4 is similar to SOT-23-5 Circuits using microcontrollers or logic circuits that require and SC-82 respectively (JEDEC) a reset.
