Description
Current Return For High-Side Gate Drive.
High-Side Gate Drive Output.
High-Side Bootstrap Supply. A capacitor from this pin to SW holds the bootstrapped voltage while
the high-side MOSFET is on.
Power Supply Input/Output of the Controller.
Voltage Identification DAC Inputs. A 5-bit word (the VID code) programs the DAC output voltage, the
reference voltage of the voltage error amplifier without a load (see the VID code table, Table 4). In
normal operation mode, the VID DAC output programs the output voltage to a value within the 0 V to
1.25 V range. The input is actively pulled down.
Enable Input. Driving this pin low shuts down the chip, disables the driver outputs, and pulls PWRGD low.
Power-Good Output. Open-drain output. A low logic state means that the output voltage is outside
of the VID DAC defined range.
Variable Frequency Enable Input. Pulling this pin to ground sets the normal RPM mode of operation.
Pulling this pin to 5 V sets the fixed-frequency PWM mode of operation.
