MAXIM INTEGRATED PRODUCTS  MAX6348UR44+T  芯片, 微处理器监控器, 5.5V, SOT-23-3

The is an ultra low power microprocessor µP reset circuit in 3 pin SOT-23 package. This supervisory circuit monitors power supplies in µP and digital systems. It provides excellent circuit reliability and low cost by eliminating external components and adjustments when used with 2.5V, 3V, 3.3V and 5V powered circuits. The circuit performs a single function that is it asserts a reset signal whenever the VCC supply voltage declines below a preset threshold keeping it asserted for at least 100ms after VCC has risen above the reset threshold. The device mostly used in computers, intelligent instruments, critical µP and µC, controllers and battery powered equipment.
