resistor and transmitted to the

SENSE4 pin.

Connecting 0.01μF to 0.1μF capacitors between the CP1 and CP2, CP3 and

CP4, and VG and GND pins generate a VG voltage of approximately VM1 +

(VCC x 2). Use caution to ensure that the voltage difference between VG and

VM is 4.5V or higher, and that the VG voltage does not exceed the absolute

maximum rating of 18V, especially BST voltage direct input.

The output current is converted to

a voltage with the RNF3 external

resistor and transmitted to the

SENSE3 pin.
