BU45K482 Datasheet | ROHM

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 2.3V to 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 V DD1 V DD2 Key Specifications - Detection voltage: 2.3V to 4.8V (Typ.) 0.1V steps - High accuracy detection voltage: ±1.0% - Low current consumption: 2.3µA (Typ.) - Operating temperature range: -40°C to +105°C - Two internal, fixed delay time: 200ms 400ms - Package SSOP3 2.92mm x 2.80mm x 1.25mm - Applications Circuits using microcontrollers or logic circuits that require a reset V DD1 BU45 xxxxx RL Micro RST controller BD46 xxxxx Micro RST controller （Noise-filtering Capacitor） （Open Drain Output Type） BU45xxxxx series - Connection...
