PIN CONNECTIONS

Table 1. 33810 Pin Definitions (continued)

A functional description of each pin can be found in the Functional Pin Description section beginning on page 15.

Pin Number Pin Name Pin Function

Formal Name

Definition

The Output Enable pin (OUTEN) is an active low input. When the OUTEN

pin is low, the device outputs are active. The outputs are disabled when

OUTEN is high.

OUTEN

MAXI

Input

Output Enable

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 General Purpose Gate pre-Driver. The MAXI

current level is determined by the voltage drop across an external sense

resistor connected to pins RSP and RSN.

Output

Maximum Ignition Coil

Current

This pin is the Nominal Ignition Coil Current output flag. This output is

asserted when the IGBT Collector-Emitter current exceeds the level

selected by the DAC.

Output

Nominal Ignition Coil

Current

In IGBT ignition gate pre-driver mode, these feedback inputs monitor the

IGBT's collector voltage to provide the spark duration timer control signal.

Input

Feedback Voltage

Sense

IGBT/General Purpose Gate pre-driver outputs are controlled by GIN0 -

GIN3. Pull-up and pull-down current sources are used to provide a

controlled slew rate to an external IGBT or MOSFET connected as a low

side driver.

Output

Gate Drive Output

This pin is the Positive input of a current sense amplifier.

This pin is the Negative input of a current sense amplifier.

These pin are the Open drain low side injector driver outputs.
