PT7M6837ID3TBEX

Supervisors Overview

The PT7M6837ID3TBEX is a fixed-channel power supply support circuit manufactured by Diodes Incorporated. It operates within an extended temperature range of -40°C to +85°C and utilizes a TSSOP-4 package. The device provides a fixed reset threshold voltage of 1.228V with a detect voltage accuracy of ±1.5%. It features low power consumption, typically 7.5μA, and offers multiple timeout periods including 70μs, 1.5ms, 30ms, 210ms, and 1.68s. The output configuration supports push-pull or open-drain RESET signals.

Supervisors Feature Summary
