RZ7899-MS

RZ7899-MS is the SOP-8 ordering code for the MSKSEMI RZ7899 brushed DC motor driver, named word-for-word throughout the manufacturer’s product specification (tube marking 7899). MSKSEMI publishes no lifecycle grading system; the code is current in that specification. The H-bridge runs from 3.0 V to 33 V, with standby current of 1 µA maximum, static current of 1.0 mA typical, an undervoltage lockout threshold of 1.9 V minimum, 2.2 V typical and 2.8 V maximum, combined high- and low-side on-resistance of 80 mΩ typical at a 1 A load, overcurrent protection at 10 A typical, thermal protection at 160 °C typical and an absolute maximum continuous output current of 8.0 A. The selection point is single-chip forward/reverse drive for small DC motors: smart locks, toys, valve and damper actuators and office equipment. Selection advice: the same device is also offered in a DIP-8 body - the -MS suffix is the SOP-8 version, so quote the suffix in full, and design the copper pour for the thermal path, since the SOP-8 case sets the practical continuous current well below the absolute maximum. Parameters verified against the MSKSEMI RZ7899 product specification (electrical characteristics and absolute maximum ratings).
