DESCRIPTION

· The U2102B is a timer control circuit based on bipolar technology.

· It can switch a MOSFET or IGBT in the output stage.

· Features two sensor inputs and adjustable, retriggerable tracking time.

· Utilizes reverse phase-control for dimming resistive loads without compensation inductance.

· Includes integrated current monitoring for fast switch-off during short-circuit conditions, eliminating the need for an additional fuse.

FEATURES

· Integrated Reverse Phase Control with modes including Zero-voltage Switch, Two-stage Reverse Phase Control with Switch-off, and Dimming Function.

· Current Monitoring with high-speed short-circuit and high-current monitoring with integrating buffer.

· Integrated Chip Temperature Monitoring.

· Adjustable and Retriggerable Tracking Time.

· External Window Adjustment for Sensor Input.

· Enable Input for Triggering Applications.

· Suitable for Two- or Three-wire Applications.

APPLICATIONS

· Motion Detectors.

· Time-delay Relays.

· Dimmers.

· Reverse Phase Controls.
