Seven low-side NMOS outputs in a 16-SOIC
The DRV777DR from Texas Instruments is a fully integrated driver that packs seven low-side NMOS outputs into a 16-SOIC package. Each channel is rated for 1A continuous output, driven by a parallel interface. The supply and load voltage range of 5V to 20V lets you run logic and power off a single rail — common in 12V and 24V industrial systems. The -40°C to 125°C junction temperature range qualifies it for motor drives, solenoid banks, relay coils, and unipolar stepper motors in factory automation or under-hood automotive environments.
1A per channel — what it means for the load
The 1A per-output rating is continuous, not pulsed. For a brushed DC motor at 12V, that's about 12W per channel — enough for small pumps, fans, or actuator drives. For unipolar stepper motors, the seven outputs let you drive a five- or six-lead motor with one phase per output, leaving headroom for a brake or indicator. The low-side configuration means the load connects between the positive supply and the drain; the source sinks to ground. Watch the total package dissipation when all seven channels run near 1A — the 16-SOIC copper pad area and airflow matter.
Active lifecycle — no LTB pressure
The DRV777DR carries an Active product status with ROHS3 compliance. No last-time-buy notice, no end-of-life risk. It remains a valid choice for new designs and production replenishment through independent distribution.
