Datasheet Motor / Actuator Drivers for DC Brush Motor Series Automotive 8ch Half Bridge Driver with SPI Control BD16938AEFV-C General Description Key Specifications The BD16938AEFV-C is 8ch half bridge driver for Supply Voltage 6.3V to 32V automotive applications. It can drive compact DC Operating Temperature Range -40C to +125C brush motors directly and each output can be Output Current 1.0A(Max) controlled in three modes (High, Low and High Output ON Resistance (High Side) 0.8(Typ) Impedance). Output ON Resistance (Low Side) 0.6(Typ) MCU can control the driver via 16bit Serial Peripheral Interface (SPI). The absolute voltage is 40V rated with low ON resistance packaged in compact package, which contributes Package W(Typ) x D(Typ) x H(Max) to realize high reliability, low energy consumption HTSSOP-B28 9.70mm x 6.40mm x 1.00mm and low cost.
