5.5 SNS

The sense (SNS) input pin monitors the user’s voltage through a resistor divider network as shown in the following figure.

To set R_TOP and R_BOTTOM, use the following equation and set an arbitrary R_TOP value greater than 100kΩ and solve for R_BOTTOM or vice versa.

Equation 5-1. Calculating R_TOP or R_BOTTOM

V_{M O N I T O R} = 0.4 V \times (1 + \frac{R_{T O P}}{R_{B O T T O M}})
