DRV8837DSGR

DRV8837DSGR is the tape-and-reel WSON-8 ordering code for the Texas Instruments DRV8837 brushed-DC motor driver, listed as ACTIVE in the datasheet package option addendum (SLVSBA4F Rev. F) with device marking 837, and shown as ACTIVE on the current TI product page. Its motor supply spans 0 V to 11 V with a separate logic supply of 1.8 V to 7 V, it drives motor current up to a 1.8 A peak - the 1.9 A figure in the datasheet is the minimum overcurrent-protection trip threshold (3.5 A maximum), not a usable output rating - its combined high-side plus low-side on-resistance is 280 mΩ typical under the datasheet test conditions, and its sleep current is 120 nA maximum, in an 8-pin WSON body of 2.0 × 2.0 mm, over -40 °C to +85 °C. The selection point is a complete H-bridge in a 2.0 × 2.0 mm footprint: battery toys, camera modules, electronic locks and small fans get forward, reverse, brake and sleep from one part whose nanoamp sleep draw does not tax a coin cell or a small lithium pack. Selection advice: at 1.8 A the 280 mΩ path resistance is the thermal story - check dissipation against the WSON’s board-dependent thermal numbers at your duty cycle, and size the VM decoupling for the stall current, not the running current. Parameters verified against the TI DRV8837 datasheet SLVSBA4F Rev. F (package option addendum and electrical characteristics).
