Pinout

Pin	Name	Functions	Notes
1	PHASE	GPIO	Controls the direction of the H-bridge
2	GND	GND	Device ground
3	nSLEEP	GPIO	Sleep mode input; logic high to enable device, low to enter sleep mode
4	ENABLE	GPIO	Enable logic input for the H-bridge
5	CP1	—	Charge pump switching node; connect a 0.1-μF X7R ceramic capacitor rated for VBB between CP1 and CP2
6	OUT+	PWM	DMOS H-bridge output; connect to motor terminal
7	SENSE	—	Sense Power Return
8	VBB	POWER	Driver supply voltage; bypass to GND with 0.1-μF ceramic capacitors plus a bulk capacitor rated for VBB
9	OUT-	PWM	DMOS H-bridge output; connect to motor terminal
10	CP2	—	Charge pump switching node; connect a 0.1-μF X7R ceramic capacitor rated for VBB between CP1 and CP2
11	MODE	GPIO	Mode logic input; controls the direction of the H-bridge in HTSSOP package, phase logic input in WQFN package
12	GND	GND	Device ground (WQFN package)
13	VCP	—	Charge pump reservoir capacitor pin; connect a X7R, 0.1-μF, 16-V ceramic capacitor to VBB
14	VREG	POWER	Regulated voltage (WQFN package)
15	nFAULT	GPIO	Fault indication; pulsed logic low with fault condition, open-drain output requires an external pullup resistor
16	PowerPAD	GND	Exposed pad for thermal dissipation; connect to ground
