Product Summary
The IMP810REUR-T is a 3.0V, 3.3V and 5.0V power supply supervisor cir-cuits optimized for low-power microprocessor (μP), microcontroller (μC) and digital systems. The IMP810REUR-T is improved drop-in replacements for the Maxim MAX809/810 and feature 60% lower supply current. A reset signal is issued if the power supply voltage drops below a preset reset threshold and is asserted for at least 140ms after the supply has risen above the reset threshold. The applications of the IMP810REUR-T include Embedded controllers, Battery operated systems, Intelligent instruments, Wireless communication systems, PDAs and handheld equipment.
