Multiple voltage regulator with switch

TDA3607

FUNCTIONAL DESCRIPTION

The TDA3607 is a multiple output voltage regulator with

three independent switchable regulators. When the supply

voltage (VP > 4.5 V) is available, regulators 1, 2 and 3 can

be operated by means of 3 independent enable inputs.

Schmitt-trigger functions are included to switch-off the

regulators at low battery voltage (VP < 4 V). A hysteresis is

included to avoid random switching.

All output pins are fully protected. The regulators are

protected against load dump (regulators will switch-off at

supply voltages higher than 20 V) and short-circuit

(foldback current protection).

The total timing of a semi on/off logic set is shown in Fig.3.
