DB PACKAGE

(TOP VIEW)

The TPIC44L01, TPIC44L02, and TPIC44L03 are

low-side predrivers that provide serial and parallel

input interfaces to control four external FET power

switches such as offered in the TI TPIC family of

power arrays. These devices are designed

primarily for low-frequency switching, inductive

load applications such as solenoids and relays.

Fault status for each channel is available in a

serial-data format. Each driver channel has

independent off-state open-load detection and

on-state shorted-load/short-to-battery detection.

Battery overvoltage and undervoltage detection

and shutdown is provided on the TPIC44L01/L02.

On the TPIC44L03 driver, only over-battery-volt-

age shutdown is provided Each channel also

provides inductive-voltage-transient protection

for the external FET.

These devices provide control of output channels through a serial input interface or a parallel input interface.

A command to enable the output from either interface enables the respective channels gate output to the

external FET. The serial interface is recommended when the number of signals between the control device and

the predriver must be minimized and the speed of operation is not critical. In applications where the predriver

must respond very quickly or asynchronously, the parallel input interface is recommended.

For serial operation, the control device must transition CS from high to low to activate the serial input interface.

When this occurs, SDO is enabled, fault data is latched into the serial interface, and the fault flag is refreshed.

Data is clocked into the serial registers on low-to-high transitions of SCLK through SDI. Each string of data must

consist of at least four-bits of data. In applications where multiple devices are cascaded together, the string of

data must consist of4 bits for each device. A high data bit turns the respective output channel on and a low data
