Figure 5. Functional Block Diagram
ANALOG CONTROL CIRCUITRY
The 33800 is designed to operate from 5.0 to 36V on the
VPWR pin. The VPWR pin supplies power to all internal
regulators, analog and logic circuit blocks. The VDD supply is
used for setting communication threshold levels and
supplying power to the SO driver. This IC architecture
provides low quiescent current Sleep Modes. Applying
VPWR to the device will cause a Power On Reset (POR). The
on-chip oscillator supports the selectable PWM frequency
and duty cycle. The on-chip voltage regulator and bandgap
supply the required voltages to the internal circuitry.
MCU INTERFACE AND OUTPUT CONTROL
The device is designed with six flexible PWM gate driver
outputs. Each driver may be controlled directly from the MCU
and may be programmed through the SPI for a specific
frequency and duty cycle.
LOW–SIDE DRIVERS: OUT1 – OUT8
The 33800 provides flexible control of 8 low side driver
outputs. Outputs 1 and 2 are specifically designed with higher
current limits to accommodate lamp inrush current. The
device allows for parallel control of the outputs or SPI control
through the use of several input command words.
CONSTANT CURRENT LOW SIDE DRIVERS: CCD1
AND CCD2
The CCD1/CCD2 constant current controllers are
switching hysteretic current controllers with a superimposed
dither. The controllers are designed to provide a
programmable constant current through a solenoid valve.
Fluid flow is controlled by the amount of current run through
the driven solenoid valve.
GATE PRE-DRIVERS: GD1 – GD6
The GD1 – GD6 pins are the gate drive outputs for external
MOSFETS. They can be PWM’ed with speed and duty cycle
choices per the SPI command registers. Internal to the device
is a Gate to Source resistor designed to hold the external
MOSFET in the OFF state while the device is in POR.
