Automotive Engine Control IC
The 33810 is an eight channel output driver IC intended for automotive engine
control applications. The IC consists of four integrated low-side drivers and four
low-side gate pre-drivers. The low-side drivers are suitable for driving fuel
injectors, solenoids, lamps, and relays. The four gate pre-drivers can function
either as ignition IGBT gate pre-drivers or as general purpose MOSFET gate
pre-drivers. This device is powered by SMARTMOS technology.
When configured as ignition IGBT gate pre-drivers, additional features are
enabled such as spark duration, dwell time, and ignition coil current sense.
When configured as a general purpose gate pre-driver (GPGD), the 33810
provides external MOSFETs with short-circuit protection, inductive flyback
protection and diagnostics. The device is packaged in a 32 pin (0.65mm pitch)
exposed pad SOIC.
Features
• Designed to operate over the range of 4.5 V VPWR 36 V
• Quad ignition IGBT or MOSFET gate pre-driver with parallel/SPI and/or PWM
control
• Quad injector driver with parallel/SPI control
• Interfaces directly to MCU using 3.3 V/5.0 V SPI protocol
• Injector driver current limit - 4.5 A max.
• Independent fault protection and diagnostics
• VPWR standby current 10 A max.

Resistor Sense
Positive
This pin is the Positive input of a current sense amplifier.
Resistor Sense
Negative
This pin is the Negative input of a current sense amplifier.
Nominal Ignition Coil This pin is the Nominal Ignition Coil Current output flag. This output is asserted
Current
when the IGBT Collector-Emitter current exceeds the level selected by the DAC.
Maximum Ignition Coil
Current
This pin is the Maximum Ignition Coil Current output flag. This output is asserted
when the IGBT Collector-Emitter current exceeds the selected level of the DAC.
This signal also latches off the gate pre-drive outputs when configured as a GPGD.
The MAXI current level is determined by the voltage drop across an external sense
resistor connected to pins RSP and RSN.
Ground
The exposed pad is the only ground reference for analog, digital and power ground
connections. As such, it must be soldered directly to a low-impedance ground plane
for both electrical and thermal considerations. For more information about this
package, see application note AN2409 on the Freescale web site,
