• Manufacturer Part Number: NCV7708A
• Description: The NCV7708A is a fully protected Hex Half Bridge Driver designed specifically for automotive and industrial motion control applications. The six low and high side drivers are freely configurable and can be controlled separately. This allows for high

SPI Communication
for the communication of this IC to turn drivers on and off,
and to report faults. (Reference the SPI Communication
Frame Format Diagram). The LSB (Least Significant Bit) is
clocked in first.
Standard 16−bit communication has been implemented
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. The SI input signal is latched on
the falling edge of SCLK.

the above conditions and a complete set of
multiples of 16 bit words.
