ISL6127IRZA

Power Supply Controllers, Monitors Overview

The ISL6127IRZA is a four-channel power sequencer manufactured by Intersil, now part of Renesas Electronics. It operates within a supply voltage range of 1.5 V to 5.5 V and features adjustable under-voltage lockout thresholds starting from 700 mV. The device monitors four independent inputs without manual reset or watchdog timer functionality. Designed for surface-mount installation in a QFN-EP-24 package, it supports an operating temperature range from -40°C to +85°C with a typical quiescent current of approximately 100 µA.
