NCV7608
DETAILED OPERATING DESCRIPTION
Normal Operation
Power Outputs
The NCV7608 provides eight independent power
transistors with pins D1 ? D8, and S1 ? S8 as drain and source
outputs respectively. For High ? side Drive configurations
(sourcing), the drain pins are connected to the battery supply.
In Low ? Side configurations (sinking), the drain pins are
connected to the load. All outputs may be configured as
high ? side, low ? side, half ? bridge, or H ? bridge. Internal
clamping structures are provided to limit transient voltages
when switching inductive loads.
CSB
SPI ? Interface
The device provides a 16 bit SPI ? interface. Data is
imported into the NCV7608 through the SI (serial input) pin.
Data is exported out of the NCV7608 through the SO (serial
output) pin. The input ? frame (SI) is used to command the
output stages and program individual channel open load
diagnostics. The response frame (SO) provides
channel ? specific (1bit / channel) status information and
fault information. See Table 1 for channel status decoding.
Words should be composed of 16 bits LSB (least significant
bit) transmitted first.
