Product Summary

The TDA3619 is a multiple output voltage regulator with power switches, intended for use in car radios with or without a microprocessor.


Parametrics

TDA3619 absolute maximum ratings: (1)load dump protection t 50 ms; tr 2.5 ms: - 50 V; (2)Vrp reverse polarity voltage non-operating: -18 V; (3)Ptot total power dissipation Tamb = 25 °C: 62.5 W; (4)Tstg storage temperature non-operating: -55 to +150 °C; (5)Tamb ambient temperature operating: -40 to +85 °C; (6)Tj junction temperature operating: -40 to +150 °C.

Features

TDA3619 features: (1)Six voltage regulators; (2)Five microprocessor controlled regulators (regulators 2 to 6); (3)Regulator 1 and reset operate during load dump and thermal shutdown; (4)Low reverse current of regulator 1; (5)Very low quiescent current when regulators 2 to 6 and power switches are switched off (VI(ig)= 0 V); (6)Reset output; (7)Adjustable display regulator; (8)High ripple rejection; (9)Three power switches; (10)Low noise for regulators 2 to 6.
