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.","metaTitle":"DRV777DR 7-Ch Low-Side Driver, 1A, 5-20V, 16-SOIC","metaDescription":"DRV777DR 7-channel low-side NMOS driver, 1A per output, 5-20V supply, -40°C to 125°C, 16-SOIC.

They are not pin-compatible or direct equivalents. No official second-source alternate is listed for the DRV777DR."},{"question":"Can I use DRV777DR for a stepper motor?","answer":"Yes, the DRV777DR is specified for unipolar stepper motors. Its seven low-side outputs can drive a five- or six-lead unipolar stepper with one phase per output, plus an extra channel for a brake or indicator. It is not suited for bipolar stepper motors, which require H-bridge outputs."},{"question":"What are the specifications of DRV777DR?","answer":"The DRV777DR is a fully integrated driver with seven low-side NMOS outputs rated at 1A each.
