Dual H-bridge driver for 3.5 A loads
The Texas Instruments DRV8842PWPR is a fully integrated motor driver combining control logic and a power stage in a single 28-PowerTSSOP package. It drives one bipolar stepper motor or two brushed DC motors using two internal N-channel Power MOSFET half-bridges. The parallel interface accepts step/direction or phase/enable signals directly from a microcontroller or indexer without external sequencing logic. Supply and load share a single rail from 8.2 V to 45 V. The output is rated for 3.5 A continuous. Junction temperature spans -40°C to 150°C.
Active, no LTB risk
The DRV8842PWPR carries an Active lifecycle status and ROHS3 compliance. The part is available through independent distribution; current pricing and lead time are confirmed at quote time against an RFQ. For dual-sourcing, the DRV8811PWPR is a functional peer with four half-bridges and a lower 1.9 A output — not a pin-for-pin drop-in, but a valid alternative for lower-current designs.
