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.
