8.3.4 Shutdown Function

The TLV1805 has a logic level SHDN input. When the shutdown SHDN input is 1.4V above V-, the TLV1805 is disabled. When disabled, the output becomes high impedance (Hi-Z), and the supply current drops to below 10µA. The input bias current remains unchanged. Voltages may still be applied to the comparator inputs as long as V+ power is still applied and the applied input voltages are still within the specified input voltage range.

CAUTION

The maximum voltage on the shutdown pin is +5.5V referred to V-, regardless of supply voltage. Connect the SHDN pin to V- if shutdown is not used. Do not float the SHDN pin.

A high value pull-up or pull-down resistor on the output may be required if a specific logic level is required during shutdown (when the output is High-Z). This prevents logic inputs from floating to illegal states when the comparator output is in High-Z mode.

Since the Shutdown threshold voltage is a tested parameter, the shutdown pin can also be used as a second comparison input to provide a secondary measurment, such as overvoltage monitoring, as shown in the P-Channel Reverse Current Protection With Overvotlage Protection circuit.
