监控器, 手动, 推挽, 700 mV至5.5 V电源, 2.93 V阈值, 150 ms延迟, SOT-143-4

The from Products is a low power, microprocessor µP reset circuit with manual reset in 4 pin SOT-143 package. This low cost µP supervisory circuit monitors the power supplies and digital systems. It increase circuit reliability and reduce cost by eliminating external components and adjustments. They also feature a debounced manual-reset input. IC perform a single function that it assert a reset signal whenever the VCC supply voltage declines below a preset threshold or whenever manual reset is asserted. Reset remains asserted for a preset timeout period after VCC has risen above the reset threshold or after manual reset is deasserted. Typical applications include computers, controllers, intelligent instruments, critical µP/µC power monitoring and portable/battery-powered equipment.
