Function
A capacitor must be connected between this pin and the signal ground. It sets
the time in which the phase difference between bridge halve A and bridge
halve B is swept down from regulation level to zero or swept up from zero to
regulation level during PWM dimming.
If a capacitor is connected between this pin and the signal ground, it sets the
frequency of the PWM oscillator.
If this pin is connected to signal ground the internal PWM oscillator is
disabled.
By connecting this pin to the SYNC-pins of other ICs, they can synchronise
their hf-oscillators. Also the IC can synchronise to an external pulse source
connected to this pin.
The IC signals a fault condition to an external circuit by pulling this pin low and
external circuits can also signal a fault condition to the IC by pulling this pin
low.
The dutycycle of the internally generated PWM signal is proportional to the
voltage on this pin.
Digital output of internally generated PWM signal if a capacitor is connected to
the CPWM-pin.
Digital input of PWM signal if the CPWM-pin is connected to signal ground.
Note that the signal on the PWMd-pin is active low, so low voltage on the
PWMd-pin means lamps are on.
A buffer capacitor must be connected between this pin and the SHB-pin. This
capacitor is charged when the low side switch B is on and supplies the high
side driver B.
Return for high side gate driver B. Must be connected to the source of the high
side power switch of full bridge halve B.
HV spacer pin
A low voltage on this pin will reset and shutt down the IC
IC supply
A buffer capacitor must be connected between this pin and power ground
Gate connection of the low side power switch of full bridge halve B
return for low side drivers A and B
Gate connection of the low side power switch of full bridge halve A
HV spacer pin
Return for high side gate driver A. Must be connected to the source of the high
side power switch of full bridge halve A.
A buffer capacitor must be connected between this pin and the SHA-pin. This
capacitor is charged when the low side switch A is on and supplies the high
side driver A.
