Triple voltage and current supervisor
The TSM111 integrated circuit incorporates all sensing circuit to control a triple output power supply. This circuit is designed to be used in SMPS for Desktop PC, to supervise currents and voltages of all outputs and generate power good information to the system while managing all timing during transitory operation. It includes comparators, voltage references and matched resistors bridge for overcurrent and overvoltage detection without the need of any external components. Timing generator with external capacitors, control turn On and Off delays. It provides an integrated and cost effective solution for simultaneous multiple voltage control. The IC also manages the standby mode of SMPS while the PC is in sleep mode. TSM111 is an ideal supervisor IC for PC power supplies.
