NCV7703B
Triple Half-Bridge Driver
with SPI Control
The NCV7703B is a fully protected Triple Half−Bridge Driver
designed specifically for automotive and industrial motion control
applications. The three half−bridge drivers have independent control.
This allows for high side, low side, and H−Bridge control. H−Bridge
control provides forward, reverse, brake, and high impedance states.
The drivers are controlled via a standard Serial Peripheral Interface
(SPI). This device is fully compatible with ON Semiconductor’s
NCV7708 Double Hex Driver.

SPI Communication
Standard 16−bit communication has been implemented to
this IC to turn drivers on/off, and to report faults. (See
Figure 11). The LSB (Least Significant Bit) is clocked in
first.
Communication is Implemented as Follows:
1. CSB goes low to allow serial data transfer.
2. A 16 bit word is clocked (SCLK) into the SI
(Serial Input) pin.
3. CSB goes high to transfer the clocked in
information to the data registers.
NOTE: SO is tristate when CSB is high.
CSB
Frame detection starts
after the CSB falling edge
and the SCLK rising edge.
Frame Detection
Input word integrity (SI) is evaluated by the use of a frame
consistency check. The word frame length is compared to an
h x 16 bit acceptable word length before the data is latched
into the input register. This guarantees the proper word
length has been imported and allows for daisy chain
operation applications.
The frame length detector is enabled with the CSB falling
edge and the SCLK rising edge.
SCLK must be low during the CSB rising edge. The fault
register is cleared with a valid frame detection. Existing
faults are re−latched after the fault filter time.
Frame detection mode ends with
CSB rising edge.

Figure 11. SPI Communication Frame Format
Table 1 defines the programming bits and diagnostic bits.
Figure 11 displays the timing diagram associated with
Table 1. Fault information is sequentially clocked out the
SO pin of the NCV7703B as programming information is
clocked into the SI pin of the device. Daisy chain
communication between SPI compatible IC’s is possible by
connection of the Serial Output pin (SO) to the input of the
sequential IC (SI) (Reference the Daisy Chain Section).
