U2102B-MFPG3Y

Application Specific Clock/Timing Overview

The U2102B-MFPG3Y is a sensor control timer integrated circuit manufactured by Microchip Technology, designed for triac or relay applications. It operates within an ambient temperature range of -40°C to +125°C and is housed in an 8-MSOP package with a maximum height of 1.2 mm. The device supports two-wire or three-wire configurations and features adjustable tracking time windows for sensor input monitoring. Key internal functions include enable inputs for triggering, internal noise suppression with a 40 ms duration, and retrigger blocking set at 640 ms. This component serves as a dedicated timing solution for motion detectors and touch sensors.
