TDA3604Q; TDA3604TH

Notes to the characteristics

1. Minimum operating voltage, only if VP has exceeded 6.5 V.

2. Enable inputs of regulator 1, ignition and power switch are low. Regulator 2 is unloaded.

3. Voltage drop due to load condition.

4. The spread on tracking is one sigma value.

5. Ignition output voltage will be less than or equal to the output voltage of regulator 2.

6. IREG1 = 5 mA unless otherwise specified.

7. The drop-out voltage of regulator 1 is measured between VP and VREG1.

8. At current limit, IREGm is held constant (see Fig.5).

9. The foldback current protection limits the dissipated power at short-circuit (see Figs 5 and 6).

10. The cross talk of regulator 1 is measured with an IREG2 = 0.5 mA up to 30 mA and input frequency of fi = 100 kHz.

11. IREG2 = 5 mA unless otherwise specified.

12. The drop-out voltage of regulator 2 is measured between VP and VREG2.

13. The cross talk of regulator 2 is measured with an IREG1 = 0.5 mA up to 100 mA and input frequency of fi = 100 kHz.

14. The drop-out voltage of the power switch is measured between VI(sw) and VO(sw).

15. The delay time depends on the value of the capacitor: t
