Description
Output of inverting-input stage (Channel 2)
Negative input of inverting op-amp with 2.5VDC of bias (Channel 2)
Bandgap reference times two (typically 2.5VDC). Used to set the common
mode voltage for the input op amps. This pin is not capable of driving external
circuitry.
Internal mode selection. This pin must be connected to 0V or 5V for proper
device operation. Typically, this pin is connected to V5.
Analog Ground
5 Volt power supply input.
Break-before-make timing control to prevent shoot-through in the output
MOSFETs. Please refer to the Application Information for additional
information.
10V under-voltage fault pin (requires pull-up resistor)
Over-current detect pins (Channel 1)
Ground Kelvin feedback (Channel 1)
Negative switching feedback (Channel 1)
Power Ground
High side gate drive output (Channel 1)
Low side gate drive output (Channel 1)
Low side gate drive output (Channel 2)
High side gate drive output (Channel 2)
Power Ground
10 Volt power supply input. Used for gate drive circuitry.
Ground Kelvin feedback (Channel 2)
Negative switching feedback (Channel 2)
Over-current detect pins (Channel 2)
A logic high output indicates an under-voltage (5V or 10V), over-current or
over-temperature condition (requires pull-down resistor).
5 Volt power supply input.
Over-Current Detect pin (Channel 2). This pin must be connected to AGND for
proper device operation.
Internal bandgap reference voltage; approximately 1.0 VDC.
Over-Current Detect pin (Channel 1). This pin must be connected to AGND
for proper device operation.
Substrate (connect to AGND)
Negative supply voltage sense input. This pin is used for both over and under
voltage sensing for the VNN supply.
A logic low output indicates the input signal has overloaded the amplifier.
Positive supply voltage sense input. This pin is used for both over and under
voltage sensing for the VPP supply.
Analog Ground
Analog Ground
5 Volt power supply input.
5 Volt power supply input.
Output of inverting-input stage (Channel 1)
Negative input of inverting op-amp with 2.5VDC of bias (Channel 1)
When set to logic high, both channels are in idle mode. When low (grounded),
both channels are fully operational (connect to FAULT pin).
Not Connected internally. These pins may be grounded or left floating on the
PCB layout.
