MAX6315US29D2+T

The MAX6315US29D2+T is a low-power CMOS microprocessor supervisory circuit designed by AD for monitoring power supplies in microprocessor and digital systems. It ensures reliable system operation with minimal power consumption, featuring a precision, factory-set VCC reset threshold of 2.9V and a reset timeout period of 1ms.

This device provides excellent circuit reliability by eliminating external components and adjustments. It asserts a reset signal whenever the VCC supply voltage falls below the preset threshold or when manual reset is asserted. The reset remains asserted for an internally programmed interval after VCC has risen above the threshold or manual reset is deasserted. The open-drain RESET output can be pulled up to a voltage higher than VCC.

Applications for the MAX6315US29D2+T include computers, controllers, intelligent instruments, critical µP and µC power monitoring, and portable/battery-powered equipment. It is immune to short VCC transients and guaranteed over temperature. The device comes in a space-saving 4-pin SOT-143 surface-mount package and operates with a typical supply current of 5µA.

Key features include precision, factory-set VCC reset thresholds, four available reset timeout periods (1ms, 20ms, 140ms, or 1120ms min), and an open-drain RESET output that can exceed VCC. It is also pin compatible with the MAX811.
