GLF1401 Pin‑to‑Pin Replacement for TI TPS22966/68/76 Switches
The GLF1401 from GLF presents a compelling drop-in alternative to Texas Instruments’ widely used TPS22966DPUR, TPS22968NQDMGRQ1, and TPS22976DPUR load switches.
Product Overview
The GLF1401 is a dual-channel integrated load switch featuring VariRise™ technology, which enables programmable control of the output voltage slew rate. It supports an input voltage range of 0.6 V to 5.5 V and delivers a continuous current capacity of 6 A per channel.
TI TPS2296x/22976 Series Overview
TPS22966DPUR: A 4-A dual-channel load switch with adjustable slew rate, packaged in a 3 mm × 2 mm WSON-14
TPS22968NQDMGRQ1: An automotive-grade 4-A variant, qualified to AEC-Q100 Grade 1, in WQFN-14 package
TPS22976DPUR: A 6-A high-current load switch with reverse-current blocking capability and a low on-resistance of 14 mΩ
