Application information

4.1

Operating voltages

The TSB572 can operate from 4 V to 36 V. The parameters are fully specified for 4 V, 12 V,

and 36 V power supplies. However, the parameters are stable in the full VCC range.

Additionally, the main specifications are guaranteed in extended temperature ranges from

-40 to 125 °C.

4.2

Input pin voltage ranges

The TSB572 has internal ESD diode protection on the inputs. These diodes are connected

between the inputs and each supply rail to protect the input transistors from electrical

discharge.

If the input pin voltage exceeds the power supply by 0.2 V, the ESD diodes become

conductive and excessive current can flow through them. Without limitation this over

current can damage the device.

In this case, it is important to limit the current to 10 mA, by adding resistance on the input

pin, as shown in Figure 35: "Input current limitation".

Rail-to-rail input

The TSB572 has rail-to-rail inputs. The input common mode range is extended from

(VCC-) - 0.1 V to (VCC+) + 0.1 V at T = 25 °C.
