Apr. 2003 R5531V002 PCMCIA Power Controller ■DESCRIPTION The R5531V002 switches between the three VCC voltages (0V/3.3V/5.0V) and the VPP voltages (off/0V/3.3V/5.0V). If VCC pin or VPP pin may be clamped to the GND, short current limit works at 1A(Min.) for VCC and 0.2A(Min.) for VPP. The R5531V002 is suitable for standard PCMCIA power controllers. ■FEATURES ● ● ● ● ● ● ● Low on resistance P-channel MOSFET Switch Over- Current Limit Protection Thermal Shutdown Protection Built-in Open-drain Flag Pin Low Consumption Current Break-Before-Make Switching SSOP-16 pin Package ■APPLICATIONS PC card Power Supply Pin Voltage Switch Card-bus Slot Power Supply Control PC Card Reader/Writer ■ PIN CONFIGURATION (Top view) VCC 5_EN 1 16 GND VCC 2 15 VCC5 IN EN0 3 14 VCC OUT EN1 4 13 VCC5 IN FLG 5 12 VCCOUT NC 6 11 VCC3 IN NC 7 10 NC VPPOUT 8 9 3_EN Rev. 1.10 VCCOUT -1- ■ BLOCK DIAGRAM VPPOUT VCC5 IN VCCOUT VCC 3IN EN1 EN0 GATE CONTROL VCC5_ EN CURRENT LOGIC VCC3_EN GND LIMIT FLAG CONTROL THERMAL SHUTDOWN FLG LOGIC ■ ABSOLUTE MAXIMUM RATINGS Symbol Rating Topt=25°C Unit Input Voltage(5V) Vcc5 -0.3 to 6.0 V Input Voltage(3V) Vcc3 -0.3 to 6.0 V VFLG -0.3 to 6.0 V VIN -0.3 to 6.0 V Item Flag Voltage Logic Input Voltage Output Current Power Dissipation IO(VCC) >1A Internal Limited IO(VPP) >200mA Internal Limited PD Operating Temperature Range Topt -40 to 85 °C Storage Temperature Range Tstg -55 to 125 °C [Note] Absolute maximum ratings are threshold limit values that must not be exceeded even for any moment under any conditions.

Without being VCCOUT=0V, if commanded to immediately switch from 5V to 3.3V or vice versa, enhancement of the second switch begins after the first is OFF, realizing "break-before-make switching". In case that an OUT pin may be clamped to the GND, if over-current would continue, the temperature of the IC would increase drastically. If the temperature of the IC is beyond Typ. 135°C, the switch transistor turns off. Then, when the temperature of the IC decreases by approximately 10°C, the switch transistor turns on. Unless the abnormal situation of OUT pin is removed or turned off, the switch transistor repeats on and off. Short over-current level is set internally in the IC. There are two types of response against over-current: (1) Under the condition that OUT pin is short or large capacity is loaded, if the IC is enabled, the IC becomes constant current state immediately. Current level of constant current is short current limit. (2) While the switch transistor is on, if OUT pin is short or large capacity is loaded, until the current limit circuit responds, large transient current flows. The transient current depends on the impedance between the power supply circuit, VCC5IN/VCC3IN and load capacitance. In other words, the transient current depends on the transient response characteristics of the power supply circuit, VCC5IN/VCC3IN, PCB layout, and the connector of the card. After the transient current is beyond the current limit threshold and current limit circuit responds, the IC becomes into the constant current mode, and the current level is equal to short current limit. 12345 Rev. 1.10 -5- (2) Typical Application 1 VCC_5V VCC_3.3V 0.1µF 0.1µF 11 VCC3IN 13 VCC5IN 15 VCC5IN 6 NC 4 EN1 3 EN0 2 VCC3_EN 1 VCC5_EN Control Input1 Control Input2 Control Input3 Control Input4 14 VCCOUT 12 VCCOUT 9 VCCOUT CVCC 8 CVPP VPPOUT NC 10 7 NC FLG 5 GND 16 R5531V002 (3) Typical Application 2 VCC_12V VCC_5V 0.1µF VCC_3.3V 0.1µF 0.1µF 11 VCC3IN 13 VCC5IN 15 VCC5IN 6 NC Control Input1 Control Input2 Control Input3 Control Input4 4 EN1 3 EN0 2 VCC3_EN 1 VCC5_EN 14 VCCOUT 12 VCCOUT 9 VCCOUT CVCC 8 CVPP VPPOUT NC 10 7 NC FLG 5 GND 16 R5531V002 (Note1) Control Input 1 through 4 means a signal from PCMCIA controller.

(Refer to the block diagram.) Therefore, even If the switch may be disabled, in case the OUT voltage is higher than VCC5IN, some current flows from OUT to VCC5IN. ■ TYPICAL CHARACTERISTICS 1) Supply Current ICC5 vs. Temperature 40 14 VCC5IN=5V VCC3IN=3.3V VCC5IN=5V VCC3IN=3.3V 12 Supply Current Icc3 [µA] 35 Supply Current Icc5 [µA] 2) Supply Current ICC3 vs. Temperature 30 25 20 15 10 5 0 10 8 6 4 2 0 -50 -25 0 25 50 75 100 -50 Temperature Topt [°C] -25 0 25 50 75 100 Temperature Topt [°C] 12345 Rev. 1.10 -7- 2200 VCC5IN=5V VCC3IN=3.3V 2000 1800 1600 1400 1200 1000 -50 -25 0 25 50 75 4) Short Current Limit vs. Temperature (Select VCCOUT=3.3V) Short Current Limit ICCSC [mA](3.3V SW) Short Current Limit ICCSC [mA](5V SW) 3) Short Current Limit vs. Temperature (Select VCCOUT=5V) 2200 VCC5IN=5V VCC3IN=3.3V 2000 1800 1600 1400 1200 1000 -50 100 -25 Temperature Topt [°C] VCC5IN=5V VCC3IN=3.3V 400 300 200 100 0 -50 -25 0 25 50 75 500 400 75 100 300 200 100 0 -50 100 -25 0 25 50 75 100 Temperature Topt [°C] 7) VCCOUT Switch Resistance vs. Temperature (Select VCCOUT=5V) 8) VCCOUT Switch Resistance vs. Temperature (Select VCCOUT=3.3V) 180 180 VCC5IN=5V VCC3IN=3.3V IOUT=1A 160 140 Vccout Switch Resistance RoVcc [mΩ](3.3V SW) Vccout Switch Resistance RoVcc [mΩ](5V SW) 50 VCC5IN=5V VCC3IN=3.3V Temperature Topt [°C] 120 100 80 60 40 VCC5IN=5V VCC3IN=3.3V IOUT=1A 160 140 120 100 80 60 40 -50 -25 0 25 50 75 100 -50 Temperature Topt [°C] Rev. 1.10 25 6) Short Current Limit vs. Temperature (Select VCCOUT=3.3V) Short Current Limit IPPSC [mA](3.3V SW) Short Current Limit IPPSC [mA](5V SW) 5) Short Current Limit vs. Temperature (Select VPPOUT=5V) 500 0 Temperature Topt [°C] -25 0 25 50 Temperature Topt [°C] -8- 75 100 9)Vcc Turn on speed (Select VCCOUT=5V) 10) Vcc Turn off speed (Select VCCOUT=5V) EN0=0V EN1=0V VCC3_EN =5V RL=10Ω VCC5_EN (5V/div) VCC5_EN (5V/div) EN0=0V EN1=0V VCC3 EN=5V VCCOUT VCCOUT (2V/div) (2V/div) TIME (1ms/div) RL =10Ω TIME (1ms/div) 11) Vcc Turn on speed (Select VCCOUT=3.3V) 12) Vcc Turn off speed (Select VCCOUT=3.3V) EN0=0V EN1=0V VCC5_EN =5V VCC3_EN R L=10Ω VCC3_EN (5V/div) (5V/div) VCCOUT VCCOUT (2V/div) (2V/div) TIME (1ms/div) EN0=0V EN1=0V VCC5_EN=5V RL =10Ω TIME (1ms/div) 12345 Rev. 1.10 -9-
