STANDBY APPLICATION

The two operators of the TS902 are both put on STANDBY.

In this configuration (standby ON) :

u The total consumption of the circuit is considerably reduced down to 0.5

µA (V

CC = 3V).

This standby consumption vs V

CC curve is given figure 1b.

u The both outputs are in high impedance state.

No output current can then be sourced or sinked by the device.

The standby pin 1 should never stay unconnected.

u The “standby OFF” state, is reached when the pin 1 voltage is higher than V

in SBY/OFF.

u The “standby ON” state is assured by a pin 1 voltage lower than V

in SBY/ON.
