BU45K252G-TL

Supervisors Overview

The BU45K252G-TL is a fixed-delay voltage detector manufactured by Rohm Semiconductor. It features an under-voltage detection voltage of 2.5V with a precision of ±1%. The reset active voltage range spans from 0.6V to 6V, utilizing an open-drain output type. The device incorporates a fixed delay timer of 200msec and maintains a low reset active state. Circuit current consumption is 2.3μA in the ON state and 2.8μA in the OFF state. Hysteresis voltage is defined as VDET multiplied by 0.05. The component operates within a temperature range of -40°C to 105°C and is housed in an SSOP3 package.
