Earlier, unverified datasheets claimed a standby current as low as 1µA. Our verified measurements show a minimum of 2.2µA at 25°C, increasing to 3.8µA at 85°C. Design for 4.0µA maximum to ensure margin. Pin Configuration and Verified Functions The NPCT750 is available in a 16-pin QFN (3x3mm) or TSSOP-16EP (exposed pad) package. Below is the verified pinout:
