BASIC OPERATING DESCRIPTION
Introduction
The NCV7510 is designed for use as a predriver for
solenoids or other inductive loads requiring a “peak and
hold” function. It contains all the necessary circuitry for
programming various attributes of the peak and hold events.
These attributes include the current levels of the peak (or
pullin) event, the current levels of the hold event and the
dwell time of the pullin event (See Figure 10 Waveforms).
The attribute values are written into appropriate registers in
the NCV7510 via a 16bit SPI interface. The peak and hold
event is directly initiated and determined by the inputs to the
ENA and CONTROL pins. By applying a logic high level to
these inputs, the user has precise control over how long the
solenoid will be activated.
The dwell time base for the pullin event is provided to the
IC’s PCLK input by the user, and may be programmed by a
register bit to either be derived from a clock signal or be level
controlled. When driven by a clock signal, the drive mode
will automatically change from the peak to the hold event
when the dwell time expires. When level controlled, the
drive mode will change according to the logic state of the
PCLK input. Bringing the ENA or CONTROL input low
before the dwell time expires will terminate the peak event
and turn off the predrivers. Figure 10 shows the general
behavior of the NCV7510.
