Circuit
33800
The 33800 is a combination output switch and driver Integrated
Circuit (IC) which can be used in numerous powertrain applications.
The IC contains two programmable constant current drivers (CCD),
an octal, low side, serial switch (OSS), and six, external MOSFET
gate pre-drivers (GD). The IC has over-voltage, under-voltage, and
thermal protection. All drivers and switches, including the external
MOSFETs, have over-current protection, off-state open load
detection, on-state shorted load detection, and fault annunciation via
the serial peripheral interface (SPI).
Additional features include: Low power Sleep Mode, Heated
Exhaust Gas Oxygen (HEGO) sensor diagnostics, output control via
serial and/or parallel inputs, PWM capability, and programmable
current output with dithering. These features, along with cost effective
packaging, make the 33800 ideal for Powertrain Engine Control
applications.

PIN CONNECTIONS
Table 1. 33800 Pin Definitions(continued)
A functional description of each pin can be found in the Functional Pin Description section beginning on page 16.
Pin Number Pin Name Pin Function Formal Name
Definition
15
P7
Input
Input Seven
Input control of OSS output 7. When configured via the SPI, P7 input may
be used to control OSS output 7 and output 8 in parallel.

PWMX
Input
Pulse Width
Modulated Input
The PWMX input pin is used for direct parallel control of the GDX (Gate
Drive Output X) predriver or as on/off control of the internal PWM
controller. Control strategy is programmed via the SPI.
22 CCD2_GND Ground
CCD2 Ground
The CCD2_GND pin provides a dedicated ground for the CCD2 constant
current controller
23
CCD2_OUT Output
Current Controlled The CCD2_OUT pin is connected to a series internal sense resistor and
Driver 2 Output
power MOSFET driver. The CCD2_OUT has a pull up and pull down
current source and is used for fault threshold monitoring.
24
CCD2_REC
Input
Current Controlled The CCD2_REC pin provides a recirculation path for the load current.
Driver 2 Recirculation The CCD2_REC pin is connected to the node between the internal sense
Input
resistor and power MOSFET driver. The device uses the differential
voltage between CCD2_REC and CCD2_OUT to determine the load
solenoid current.
25
EN Input
ENABLE
The EN pin is an active high input.
26
RI_REF
Output
Resistor for Current The RI_REF pin is used to generate a reference current. The reference
Reference
is used in the regulation of the constant current controller. The constant
current controller regulation current is inversely proportional to the
reference current through the external resistor. A 39.2k1% resistor to
ground will set the 1FF programmed current value of the CCD1 to
1075mA and the CCD2 to be 232mA.
27
CCD1_OUT Output
Current Controlled The CCD1_OUT pin is connected to a series internal sense resistor and
Driver 1 Output
power MOSFET driver. The CCD1_OUT has a pull up and pull down
current source and is used for fault threshold monitoring.

CCD1_REC
Input
Current Controlled The CCD1_REC pin provides a recirculation path for the load current.
Driver 1 Recirculation The CCD1_REC pin is connected to the node between the internal sense
Input
resistor and power MOSFET driver. The device uses the differential
voltage between CCD1_REC and CCD1_OUT to determine the load

30 VPWR Power Input Analog Voltage Supply The VPWR pin provides power to all pre-driver, driver and output circuits
and other internal functions such as the oscillator and SPI circuits.
31
GND
Ground
Ground
Analog ground for the internal control circuits of the IC. This ground
should be used for decoupling of VDD and VPWR supply.
32
VCAL
Input
Voltage Calibrated VCAL input is a precision (2.5V, +8.0mV, -20mV over temperature)
Input
reference input, used in several internal circuits. A 1.0nF to 10nF
decoupling capacitor is required on the VCAL input pin to ground.
33
VDD
Power Input Digital Voltage Supply The VDD pin supplies power to the Serial Output (SO) buffer along with
the pull up current sources for the chip select (CS) and DEFAULT inputs.
34
SO
Output
Serial Output Data The SO output pin is used to transmit serial data from the device to the
MCU. The SO pin remains tri-stated until selected by the active low CS.
The serial output data is available to be latched by the MCU on the rising
edge of SCLK. The SO data transitions on falling edge of the SCLK.
