POWER SUPPLY/POR
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 a low quiescent current sleep mode. Applying
VPWR and VDD to the device will generate a Power On
Reset (POR) and place the device in the Normal State. The
Power On Reset circuit incorporates a timer to prevent high
frequency transients from causing a POR.
MCU INTERFACE AND OUTPUT CONTROL
OUT3 low side drivers and GD0-GD3 gate drivers. Each
parallel input control pin is active high and has an internal
pulldown current sink. The parallel input data is logically OR’d

outputs. The drain voltage is actively clamped during turn off
of inductive loads. These outputs can be connected in
parallel for higher current loads, provided the turn off energy
rating is not exceeded.
IGNITION GATE PRE-DRIVERS: GD0 – GD3
MOSFET or IGBT. Internal to the device is a Gate to Source
resistor designed to hold the external device in the OFF state
while the device is in the POR or Sleep State.
These pins are the Open drain low side (Injector) driver
