detailed description
sense-voltage setting
The SENSE terminal input voltage, Vs, of the TL7700 typically is 500 mV. By using two external resistors, the
circuit designer can obtain any sense voltage over 500 mV. In Figure 19, the sensing voltage, Vs’, is calculated
as:
Vs’ = Vs × (R1 + R2)/R2
Where:
Vs = 500 mV, typically at TA = 25°C
At room temperature, Vs has a variation of 500 mV ± 5 mV. In the basic circuit shown in Figure 19, variations
of [
±5 × (R1 + R2)/R2] mV are superimposed on Vs.
