NCP4672 Linear Voltage Regulator - Dual, V and V Voltage in out Detector The NCP4672 is a dual linear voltage regulator with input voltage and output voltage detectors. This part is useful in systems where NCP4672 MAXIMUM RATINGS Rating Symbol Value Unit Input Voltage V 0.3 ~ 18 V inmax Output Voltage V 0.3 to V + 0.3 V out in Output Current 1 I 30 mA out1max Output Current 2 I 80 mA out2max Output Short Circuit Duration Infinite Power Dissipation and Thermal Characteristics SOIC8 Power Dissipation P Internally Limited W D Thermal Resistance, JunctiontoAmbient R JA Minimum Pad Size 190 C/W 2 200 mm Pad Size (Note 1) 160 C/W Thermal Resistance, JunctiontoCase 25 C/W R JC Operating Junction Temperature Range T 40 to 125 C stg Storage Temperature Range T 55 to 150 C solder Stresses exceeding Maximum Ratings may damage the device. Maximum Ratings are stress ratings only. Functional operation above the Recommended Operating Conditions is not implied. Extended exposure to stresses above the Recommended Operating Conditions may affect device reliability. 1. Refer to Figure 4 for more information. PIN DESCRIPTION Pin Number Symbol Description 1 V Opencollector, activelow output of the input voltage detector with hysteresis. Threshold levels are in RST typical 7.0 V/ 7.35 V at V pin. CC 2 V Activelow output of the reset generator. Reset generator is based on sensing of the V voltage. o RST out1 Sensing is with hysteresis threshold levels are typically 2.9 V/ 2.95 V at V . Reset is generated at out1 rising edge of the V and its duration is set by external capacitor connected to C pin. out1 D 3 C Programmable delay of the reset generator. Delay is adjusted by inserting a capacitor between C and D D GND (typically 10 ms for 10 nF capacitor). 4 V Supply Voltage CC 5 V 1.8 V/ 80 mA LDO Regulator Output out2 6 GND2 Ground for V (internally connected with GND1) out2 7 GND1 Ground for V (internally connected with GND2) out1 8 V 3.5 V/30 mA LDO Regulator Output out1 RECOMMENDED CONDITIONS (T = 25C, C = 0.1 F Ceramic, C = 4.7 F) A in out Characteristics Symbol Min Typ Max Unit Input Voltage V 3.8 12 16 V in Output Current (where V remains within accuracy) I 0 20 mA out out1 I 0 70 out2
