PIN			DESCRIPTION
NAME	NO.	TYPE	DESCRIPTION
D1	1	O	Open drain output of the first power MOSFETs. Typically connected to the outer terminals of the center tap transformer. Because large currents flow through these pins, their external traces should be kept short.
V_CC	2	P	This is the device supply pin. It should be bypassed with a 4.7 μF or greater, low ESR capacitor. When V_CC ≤ 2.25 V, an internal undervoltage lockout circuit trips and turns both outputs off.
D2	3	O	Open drain output of the second power MOSFETs. Typically connected to the outer terminals of the center tap transformer. Because large currents flow through these pins, their external traces should be kept short.
GND	4	P	GND is connected to the source of the power MOSFET switches via an internal sense circuit. Because large currents flow through it, the GND terminals must be connected to a low-inductance quality ground plane.
EN	5	I	The EN pin turns the device on or off. Grounding or leaving this pin floating disables all internal circuitry. If unused this pin should be tied directly to V_CC.
CLK	6	I	This pin is used to run the device with external clock. Internally it is pulled down to GND. If valid clock is not detected on this pin, the device shifts automatically to internal clock.
