8.3.1 Sense-Voltage Setting

The typical SENSE terminal input voltage (Vs) of the TL7700-SEP is 500 mV. By using two external resistors, the circuit designer can set the desired sense voltage to any value above 500 mV. Based on the schematic shown in Figure 8-1, the desired sense voltage (Vs') is calculated as:

Equation 1. Vs'= Vs×(R1+R2)R2

where:

  • Vs = 490 mV to 520 mV over temperature range
