Pin Description

Pulse width modulated output #1

Ground. This pin is connected to ground on the circuit board through a trace. Do not

connect directly to GND plane.

This pin should be soldered to pads on the PCB for mechanical stability. It can be electri-

cally floating or tied to VDD (do not tie to GND).

Pulse width modulated output #2

Power. This pin is connected to power on the circuit board.

Digital input that toggles between RH and temperature outputs on PWM1 and PWM2.

This pin should be pulled high or low (do not leave floating).

Paddle This pad is connected to GND internally. This pad is the main thermal input to the on-

chip temperature sensor. The paddle should be soldered to a floating pad.
