Motor / Actuator / Drivers for DC Brush Motor Series
Automotive 6ch Half Bridge Driver
with SPI Control
BD16936EFV-M
General Description
The BD16936EFV-M is 6ch Half Bridge Driver for
automotive applications. It can drive compact DC brush
motors directly and each output can be controlled in
three modes (High, Low and High Impedance). MCU
can control the driver via 16bit Serial Interface (SPI). The
part is 60V rated with Low ON Resistance packaged in
compact HTSSOP-28 package, which contributes to
realize high reliability, low energy consumption and low
cost.

Caution:
Operating the IC over the absolute maximum ratings may damage the IC. The damage can either be a short circuit
between pins or an open circuit between pins and the internal circuitry. Therefore, it is important to consider
circuit protection measures, such as adding a fuse, in case the IC is operated over the absolute maximum ratings.

In order to start operation, apply the voltage to VCC (Driver supply voltage) after VS (Power supply voltage)
exceeds the minimum operating voltage range (8V).
In order to start operation, apply the voltage to Logic input voltage after VCC (Driver supply voltage)
exceeds the minimum operating voltage range (4.5V).
