TPIC2603

6-CHANNEL SERIAL INTERFACE LOW-SIDE DRIVER

SLIS056A – FEBRUARY 1995 – REVISED MARCH 1996

POST OFFICE BOX 655303

description (continued)

When an over-current or shorted-load fault occurs, the channel transits into a low duty cycle

pulse-width-modulated (PWM) signal as long as the fault is present. More detail on fault detection operation is

presented in the device operation section of this data sheet.

The TPIC2603 provides pulldown resistors on all active-high inputs except SCLK. A pullup resistor is

used on CS.

The TPIC2603 is characterized for operation over the operating case temperature of – 40

°C to 125°C.
