CategorySemiconductors => Power Management ICs => 8841216
TitleSupervisory Circuits 2.3V 400ms SSOP3 CMOS Volt Detctr IC
DescriptionROHM Semiconductor BU45K/BU46K Series Voltage Detector ICs with built-in counter timer offer a low current consumption of 2.3?A (Typ.) and high accuracy detection voltage of 1.0%. The BU45K/BU46K Series has a detection voltage range of 2.3V to 4.8V with a counter timer delay circuit built-in, eliminating the need for an external capacitor. The BU45K/BU46K Series provides two output types, N-Channel Open Drain and CMOS Output, allowing users more flexiblity. Two internal fixed delay times are available (200ms and 400ms) as required by an application.

Features, Applications

Counter Timer Built-in CMOS Voltage Detector IC

General Description ROHM's BU45xxxxx and BU46xxxxx series are highly accurate, low current consumption voltage detector IC series. Because the counter timer delay circuit is built-in, an external capacitor for the delay time setting is unnecessary. Two output types are available (Nch open drain and CMOS output) and detection voltages range from 4.8V in increments of 0.1V with fixed delay time of 200ms and 400ms, that may be selected according to application. Features Counter Timer Built-in No delay time setting capacitor required Low current consumption Two output types (Nch open drain and CMOS output) Package SSOP3 is similar to SOT-23-3 (JEDEC) Typical Application Circuit

to 4.8V (Typ.) 0.1V steps High accuracy detection voltage: 1.0% Low current consumption: 2.3A (Typ.) Operating temperature range: +105 C Two internal, fixed delay time: 200ms 400ms
