The power supply provides regulated 5-V output to power the system microcontroller and drive eight low-side

switches. The brown-out detection output (BO_OUTZ) warns the system if there is a temporary drop in the

supply voltage, so the system can prevent potentially hazardous situations.

A serial communications interface controls the eight low-side outputs; each output has an internal snubber circuit

to absorb the inductive load at turn OFF. Alternatively, the system can use a fly-back diode to V

to help

recirculate the energy in an inductive load at turn OFF.

The open-drain power-on reset (RST) pin remains low until the regulator exceeds the set threshold, and the timer value set by the capacitor on the reset delay (RDELAY) pin expires.

A single register controls all the outputs. The signal gives the instruction to control the output of TPL9202. The NCS signal enables the SCLK and MOSI data when it is low.
