FEATURES
s Three enable pin controlled standby regulators: x REG1: 5 V / 600 mA controlled by the EN1 input x REG2: 3.3 V / 200 mA controlled by the EN2/3 input x REG3: 1.9 V / 150 mA controlled by the EN2/3 input s Four mode pin controlled switched regulators: x REG4: 8.5 V / 350 mA x REG5: 5 V / 1.8 A x REG6: 3.3 V / 1.2 A x REG7: 2.4 V to 10 V / 2 A adjustable using external resistor divider s One mode pin controlled power switch; 2.2 A continuous and 3 A surge, with delayed lower current limit so as to be less sensitive to inrush currents s One independent ignition buffer (inverted output, open-collector) with good input protection against high transients s A storage capacitor is included to provide back-up supply for the standby regulators in the event of loss of battery supply Philips Semiconductors TDA3683 Multiple voltage regulator with switch and ignition buffer s A hold output (3-state) which can be used to communicate to a microcontroller in the event of an internal or exter...
