Product Summary
The IMP809T is a 3-Pin Microcontroller Power Supply Supervisor. It is a 3.0V, 3.3V and 5.0V power supply supervisor circuit optimized for low-power microprocessor (μP), microcontroller (μC) and digital systems. The IMP809/810 are improved drop-in replacements for the Maxim MAX809/810 and feature 60% lower supply current. Low supply current makes the IMP809T ideal for use in portable and battery operated equipment. The IMP809T is available in a compact 3-pin SOT23 package. The applications of the IMP809T include embedded controllers, Battery operated systems, Intelligent instruments, Wireless communication systems, PDAs and handheld equipment.
