Motor / Actuator Drivers for DC Brush Motor Series
Automotive 3ch Half Bridge Driver
with SPI Control
BD16933EFV-C
General Description
The BD16933EFV-C is 3ch 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-20 package, which
contributes to realize high reliability, low energy
consumption and low cost.

2. Over Voltage Protection (OVP)
All outputs run into High impedance when VS terminal voltage goes up to or above 50V (Typ). OVPS register is set “1” in
this case.
The outputs come back when VS terminal voltage goes down to or below 45V (Typ) and return to the normal operation.
The state of output data register OVPS can be either Latch or Self Recovery depending on the state of input data register
PSSTH.
Input data register PSSTH=0 and output data register OVPS=1 for Latch. Input data register PSSTH=1 and output data
register OVPS for Self Recovery when VS terminal voltage goes down to or below 45V (Typ). OVP doesn‟t operate when
EN terminal is at Low level. Be sure not to exceed the absolute maximum power supply voltage to avoid the IC being
destroyed.

3. Under Voltage Lock Out (UVLO)
All outputs run into High impedance when VS terminal voltage goes down to or below 6.0V (Typ). UVLOS register is set “1”
in this case. Outputs come back when VS terminal voltage goes up to or above 6.5V (Typ) and return to the normal
operation mode. Output data register UVLOS in this case can be either Latch or Self Recovery depending on the status of
input data register PSSTH. Input data register PSSTH=0 and output data register UVLOS= 1 for Latch. Input data register
PSSTH=1 and output data register UVLOS for Self Recovery when VS terminal voltage goes up to or above 6.5V (Typ).
