MC33874 - Functional Block Diagram
Analog Control Circuitry
ANALOG CONTROL CIRCUITRY
The 33874 is designed to operate from 6.0V to 27V 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 SPI interface logic. This IC
architecture provides a very low standby current. The analog
circuitry provides for over-current and over-temperature
protection as well as temperature warning features.
MCU INTERFACE AND OUTPUT CONTROL
The device is designed with 4 inputs for PWM Output
driver control, if desired. MCU programming, control and
diagnostics are accomplished using the 16-bit SPI interface.
Several parallel control and status lines are provided.
HIGH–SIDE DRIVERS: HS0 – HS3
The 33874 provides high side load drive capability for 4
outputs. The RDS ON for the output MOSFETs is 35m Ω . The
outputs are protected for over-current and over-temperature.
The MOSFET gate drive can be slew rate controlled using the
SPI interface. There is also an open load detection feature. A
ratioed value of the MOSFET output current is available to
the MCU.
The device allows for control of the 4 outputs through the
SPI interface or by use of the parallel inputs, which allows for
PWM capability.
