The GLF76321 / GLF76321T is an ultra-thin, ultra efficient IQSmartTM load switch with an integrated Deep Sleep timer for wearables and IoT devices. The /SRO pin enables a whole system to enter ultra deep sleep power conservation mode by disconnecting the system from the battery charge, with a ultra-low standby current of 7nA typical. This feature significantly extends system battery life in devices during shipping or periods of extended off time.

GLF_loadswitch2.pngThe ideal load switch would draw zero current when the application is in standby mode.
We believe GLF’s IQSmart™ load switches are the closest you can get to perfection.

Our ultra-efficient and compact load switches not only offer ultra-low leakage current – up to 50 times lower than other load switches – they also exhibit the lowest RDS(ON) for a given small form factor.
