TDA3681JR/N2S Allgemeine Beschreibung

Ignition Buffer, Regulator PMIC 17-PDBS

Hauptmerkmale

General
Low noise behaviour and good stability with very small output capacitors
Second supply pin for regulators 3 and 4 to reduce power dissipation (e.g. via a DC-to-DC converter)
Three V
P
Regulator 2, reset and ignition buffer operational during load dump and thermal shutdown
Combined control pin for switching regulators 1 and 3
Separate control pins for switching regulator 4 and the power switch
Supply voltage range from -18 to +50 V
Low quiescent current in standby mode (when regulators 1, 3 and 4 and power switch are switched off and ignition input is low)
Hold output (open-collector output stage) for low V
P
Hold output when one of regulators 1 and 3 and/or 4 is out of regulation
Hold output for foldback mode of power switch and regulators 1, 3 and 4
Hold output for load dump and temperature protection
Reset (push-pull output stage) for regulator 2
Adjustable reset delay time
High supply voltage ripple rejection
Backup capacitor for regulator 2
One independent ignition buffer (active HIGH).
Protections
Reverse polarity safe (down to -18 V without high reverse current)
Able to withstand voltages up to 18 V at the outputs (supply line may be short-circuited)
ESD protection on all pins
Thermal protections
Load dump protection
Foldback current limit protection for regulators 1, 2, 3 and 4
Delayed second current limit protection for the power switch (at short-circuit)
The regulator outputs and the power switch are DC short-circuit safe to ground and supply (V
