description (continued)

The TPIC43T01/02 provides pre-drive outputs to control six external N-channel FET switches connected in a

3-half H-bridge configuration to drive a 3-phase dc motor. A companion TI Power+ Arrays

™ device is available,

the TPIC1310 3-half H-bridge power array, to provide up to 2.5 A motor drive capability. The TPIC1310 is a

monolithic gate protected DMOS power array available in the TI 15-pin PowerFLEX

™ power package. The

TPIC43T01/02 gate drive outputs are designed to also drive discrete N-channel power FETs.

The TPIC43T01/02 provides onboard supervisory and shutdown logic to protect the device and motor from fault

conditions. Oscillators, charge pump, and voltage regulators have been integrated into the TPIC43T01/02 to

minimize the number of external discrete components required to support the motor system.
