Pin functions
A capacitor connected between this pin and Out
voltage slew rate.
Analog input controlling the PWM ratio. The operating range of the input
voltage is 0 to V
Output of an internal voltage reference.
TTL compatible input for switching off the output.
If this pin is connected to GND and V
frequency f
load.
Current sink and source stage connection of a triangle oscillator with
definite voltage swing.
Input of an operational amplifier for short current sensing and regulation.
Not connected
Common supply voltage input.
Common ground connection.
A capacitor connected between this pin and GND defines the protection
delay time.
Open collector monitoring output off the PowerMOS protection.
The capacitor connected between this pin and the source of the PowerMOS
allows to bootstrap the gate driving voltage.
Output for driving the gate of the external PowerMOS.
