Pinout

Pin	Name	Type	Function
1	OUTP	output	Positive haptic driver differential output; the nominal full-scale output is 2.2 VRMS (about ±10% depending on the LRA) into a 25 Ω LRA load.
2	GND	power_in	Ground reference; all voltage ratings are specified relative to system ground.
3	OUTN	output	Negative haptic driver differential output; the nominal full-scale output is 2.2 VRMS (about ±10% depending on the LRA) into a 25 Ω LRA load.
4	VDD	power_in	Supply input with a recommended range of 2.7 V to 5.2 V and an absolute maximum of -0.3 V to 6.0 V.
5	PWM	input	PWM duty-cycle input that sets vibration amplitude over 0% to 100% duty, with VIL max 0.6 V and VIH min 1.2 V, and 1.8 V compatible, 5 V tolerant logic.
6	EN	input	Active-high enable input that must stay high during braking and be taken low only after braking completes.
