TPIC9201N General Description

The ac-unit power supply with low side drive output provides regulated 5-V output to power the system microcontroller and drive up to eight inductive and/or resistive loads. The ac zero detect circuitry is monitoring the cross-over voltage of the mains ac supply. The resultant signal is a low frequency clock output on the ZVS terminal based on the ac line cycle. This information allows the microcontroller to reduce inrush current by powering loads on the ac-line peak voltage.

A serial communications interface controls the eight low side outputs; each output has an internal snubber circuit to absorb the energy in the inductor at turn OFF. Alternatively, the system can place a fly-back diode to VIN to help recirculate the energy in an inductive load at turn OFF.
