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
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 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.
