Product overview

The UT04VS50P supervises multiple power rails and provides per-channel status together with system-reset outputs. It can monitor four independent supplies for undervoltage, or pair channels to check both undervoltage and overvoltage on two supplies. Pin selections choose preset threshold sets or externally determined thresholds. Independent channel enables allow the number of monitored rails to match the system. External capacitors adjust output-response and reset timing, while a manual-reset input offers direct reset control. This consolidates monitoring and sequencing functions for processor, controller, ASIC and FPGA power systems.
