JAJSIK7 February 2020 THP210
ADVANCE INFORMATION for pre-production products; subject to change without notice.
The power-down feature on the THP210 allows the device to be put into a low power-consumption state, in which quiescent current is minimized. To force the device into the low-power state, drive the PD pin to less than 2 V less than the positive supply voltage (VVS+ – 2 V). Driving the PD pin to less than 2 V forces the internal logic to disable both the differential and common-mode amplifiers. The PD pin has an internal pullup current that allows for the pin to be used in an open-drain MOSFET configuration without an additional pullup resistor, as seen in Figure 12. In this configuration, the logic level can be referenced to the MOSFET, and the voltage at the PD pin is level-shifted to account for use with high supply voltages. Be sure to select an N-type MOSFET with a maximum BVDSS greater than the total supply voltage.
For applications that do not use the power-down feature, tie the PD pin to the positive supply voltage.
When PD is low (device is in power down) the output pins will be in a high-impedance state.
