description

The TPIC46L01, TPIC46L02, and TPIC46L03 are low-side predrivers that provide serial input interface and

parallel input interface to control six external field-effect transistor(FET) power switches such as offered in the

Texas Instruments 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 are

provided. Battery and output load faults provide real-time fault reporting to the controller. 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 channel GATE output to the

external FET. The serial input 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.

Please be aware that an important notice concerning availability, standard warranty, and use in critical applications of

Texas Instruments semiconductor products and disclaimers thereto appears at the end of this data sheet.

PRODUCTION DATA information is current as of publication date.

Products conform to specifications per the terms of Texas Instruments

standard warranty. Production processing does not necessarily include

testing of all parameters.
