Description
Device Supply Voltage. Linearly regulated from the highest of the VPx and VH pins to a
typical of 4.75 V. Note that the capacitor must be connected between this pin and GND.
A 10 μF capacitor is recommended for this purpose.
Supply Ground.
Exposed Pad. This pad is a no connect (NC). If possible, this pad should be soldered to the
board for improved mechanical stability.
1 In a typical application, all ground pins are connected together.
