It provides 0V, 3.3V, 5V, 12V and Hi-Z regulated power to the VPP pins of two PCMCIA card slots from a single unregulated 13V to 20V supply. When used in conjunction with a PC Card Interface Controller, the LT1313 forms a complete minimum component-count interface for palmtop, pen-based and notebook computers. The two VPP output voltages are independently selected by four logic compatible digital inputs which interface directly with industry standard PC Card Interface Controllers. Automatic 3.3V to 5V switching is provided by two independent comparators which continuously monitor each PC card VCC supply voltage and automatically adjust the VPP output to match the associated VCC pin voltage when the VPP = VCC mode is selected. Notebook Computers Palmtop Computers Pen-Based Computers Handi-Terminals Bar-Code Readers Flash Memory Programming Two open-collector VPP VALID outputs are provided to indicate when the VPP outputs are in regulation at 12V. The LT1313 is available in 16-pin SO packaging. , LTC and LT are registered trademarks of Linear Technology Corporation.

The supply pins should be bypassed to ground if the device is more than six inches away from the main supply capacitor. A bypass capacitor in the range of 0.1µF to 1µF is sufficient. The supply voltage to the LT1313 can be loosely regulated between 13V and 20V. VPPOUT Pins: Each regulated output supplies power to the two PCMCIA card VPP pins which are typically tied together at the socket. Each VPPOUT output is current limited to approximately 330mA. Thermal shutdown provides a second level of protection. A 1µF to 10µF tantalum output capacitor is recommended. Input Enable Pins: The four digital input pins are high impedance inputs with approximately 20µA input current at 2.4V. The input thresholds are compatible with CMOS controllers and can be driven from either 5V or 3.3V CMOS logic. ESD protection diodes limit input excursions to 0.6V below ground. W BLOCK DIAGRAM VCC Sense Pins: Two independent comparators and 4V references automatically switch the VPPOUT outputs from 5V to 3.3V depending upon the voltage sensed at the corresponding PCMCIA card socket VCC pin. The input current for these pins is approximately 30µA. For 5V only operation, connect the Sense pins directly to ground. An ESD protection diode limits the input voltage to 0.6V below ground. Ground Pins: The two ground pins must be connected together at all times. (One Channel) LOW DROPOUT LINEAR REGULATOR VS XVCC SENSE VALID Output Pins: These pins are open-collector NPN outputs which are driven low when the corresponding VPPOUT pin is in regulation, i.e., when it is above 11V. Two external 51k pull-up resistors are connected between these outputs and the same 5V or 3.3V logic supply powering the PCMCIA compatible control logic.

Input power is typically obtained from a loosely regulated input supply between 13V and 20V. The LT1313 consists of the following blocks: Two Low Dropout Voltage Linear Regulators: The heart of the LT1313 is two PNP-based low-dropout voltage regulators which drop the unregulated supply voltage from 13V to 20V down to 12V, 5V, 3.3V, 0V or Hi-Z depending upon the state of the four Enable inputs and the two VCC Sense inputs. The regulators have built-in current limiting and thermal shutdown to protect the device, the loads, and the sockets against inadvertent short circuiting to ground. Voltage Control Logic: The two VPPOUT outputs have five possible output modes: 0V, 3.3V, 5V, 12V and Hi-Z. These five modes are selected by the four Enable inputs and the two VCC Sense inputs as described by the Truth Table. VCC Sense Comparators: When the VCC mode is selected, the LT1313 automatically adjusts each regulated VPP output voltage to 3.3V or 5V depending upon the voltage present at the corresponding PC card VCC supply pin. The threshold voltage for these comparators is set at 4V and there is approximately 50mV of hysteresis provided to ensure clean switching between 3.3V and 5V. VPP VALID Comparator: Two voltage comparators monitor each output voltage when the 12V mode is selected and are driven low when the output is in regulation above 11V. These two outputs function separately.

U W U U APPLICATIONS INFORMATION The LT1313 is two voltage programmable linear regulators designed specifically for PCMCIA VPP driver applications. The device operates with very low quiescent current (60µA) in the 0V and Hi-Z modes of operation. In the Hi-Z mode, the output leakage current falls to 1µA. In addition to the low quiescent currents, the LT1313 incorporates several protection features which make it ideal for PCMCIA applications. The LT1313 has built-in current limiting (330mA) and thermal shutdown to protect the device and the socket VPP pins against inadvertent short-circuit conditions. Output Capacitance The LT1313 is designed to be stable with a wide range of output capacitors. The minimum recommended value is a 1µF with an ESR of 3Ω or less. The capacitor is connected directly between the output pin and ground. For applications where space is very limited, capacitors as low as 0.33µF can 6 be used. Extremely low ESR ceramic capacitors with values less than 1µF must have a 2Ω resistor added in series with the output capacitor. Transient and Switching Performance The LT1313 is designed to produce minimal overshoot with capacitors in the range of 1µF to 10µF. Larger capacitor values can be used with a slowing of rise and fall times. The positive output slew rate is determined by the 330mA current limit and the output capacitor. The rise time for a 0V to 12V transition is approximately 40µs and the rise time for a 10µF capacitor is roughly 400µs (see the Transient Response curves in the Typical Performance Characteristics section). LT1313 U W U U APPLICATIONS INFORMATION The fall time from 12V to 0V is set by the output capacitor and an internal pull-down current source which sinks about 30mA. This source will fully discharge a 1µF capacitor in less than 1ms. Thermal Considerations Power dissipated by the device is the sum of two components: output current multiplied by the input-output differential voltage: IOUT × (VIN – VOUT), and ground pin current multiplied by supply voltage: (IGND × VIN). The ground pin current can be found by examining the Ground Pin Current curves in the Typical Performance Characteristics section. Heat sinking, for surface mounted devices, is accomplished by using the heat spreading capabilities of the PC board and its copper traces. The junction temperature of the LT1313 must be limited to 125°C to ensure proper operation. Use Table 1, in conjunction with the typical performance graphs, to calculate the power dissipation and die temperature for a particular application and ensure that the die temperature does not exceed 125°C under any operating conditions.

Power dissipated by the device will be equal to: IOUT × (VS – VPPOUT) + (IGND × VIN) where, IOUT = 100mA VIN = 14V IGND at (IOUT = 100mA, VIN = 14V) = 5mA so, PD = 100mA × (14V –12V) + (5mA × 15V) = 0.275W Using Table 1, the thermal resistance will be in the range of 120°C/W to 131°C/W depending upon the copper area. So the junction temperature rise above ambient will be less than or equal to: 0.275W × 131°C/W = 36°C The maximum junction temperature will then be equal to the junction temperature rise above ambient plus the maximum ambient temperature or: TJMAX = 50°C + 36°C = 86°C For more detailed applications information, see the LT1312 Single PCMCIA VPP Driver/Regulator data sheet. * Device is mounted on topside. 7 LT1313 U TYPICAL APPLICATIONS Dual Slot PCMCIA Interface to CL-PD6720 VLOGIC 13V TO 20V 0.1µF 51k A_VPP_PGM VS AEN0 A_VPP_VCC AEN1 VPP1 VS AVPPOUT VPP2 + PCMCIA CARD SLOT #1 1µF 3.3V/5V AVALID VCC ASENSE LT1313 B_VPP_PGM BEN0 VPP1 BVPPOUT VPP2 + 1µF B_VPP_VCC BEN1 VPP_VALID BVALID GND 3.3V/5V BSENSE GND CIRRUS LOGIC CL-PD6720 Q1 Si9405DY Q2 Si9933DY AVCC 3V 5V + 10µF Q3 Si9933DY Q4 Si9405DY BVCC 5V 3.3V Q5 Si9933DY BVCC 3V Q6 Si9933DY 3.3V + 10µF P-CHANNEL VCC SWITCHING N-CHANNEL VCC SWITCHING USING LTC1165 INVERTING N-CHANNEL DRIVERS 5V IN1 AVCC 5V VS 5V Q1 1/2 Si9956DY OUT1 TO VCC SLOT 1 LTC1165CS8 AVCC 3V IN3 IN1 VS OUT1 Q2 Si9956DY OUT2 IN2 5V GND Q3 Si9956DY OUT3 5V Q4 1/2 Si9956DY IN2 IN3 GND OUT2 Q5 Si9956DY OUT3 Q6 Si9956DY 3.3V 8 3.3V TO VCC SLOT 2 LTC1165CS8 BVCC 3V VCC 5V AVCC 5V BVCC 5V PCMCIA CARD SLOT #2 1313 TA02 LT1313 U TYPICAL APPLICATIONS Dual Slot PCMCIA Interface to “365” Type Controller VLOGIC 13V TO 20V 51k 51k 0.1µF VS AVPPOUT VS AEN0 A_VPP_EN0 A_VPP_EN1 VPP1 VPP2 PCMCIA CARD SLOT #1 VCC + 1µF AEN1 3.3V/5V AVALID A:GP1 ASENSE LT1313 B_VPP_EN0 BEN0 B_VPP_EN1 BEN1 VPP1 BVPPOUT VPP2 + 1µF 3.3V/5V BVALID GND B:GP1 BSENSE GND PCMCIA CARD SLOT #2 VCC “365” TYPE CONTROLLER 5V VS IN1 A_VCC_EN0 5V Q1 1/2 Si9956DY G1 LTC1157CS8 Q2 Si9956DY A_VCC_EN1 IN2 GND 5V B_VCC_EN1 VS Q3 Si9956DY G1 3.3V Q4 1/2 Si9956DY LTC1157CS8 Q5 Si9956DY IN2 GND 10µF G2 5V B_VCC_EN0 IN1 + + 10µF G2 Q6 Si9956DY 1313 TA03 3.3V 9 LT1313 U TYPICAL APPLICATIONS Dual Slot PCMCIA Driver/Regulator Powered from Auxiliary Winding on 5V Inductor of LTC1142HV Dual 5V/3.3V Switching Regulator VIN 6.5V TO 18V VIN D1 MBRS140 10 + Q1 PDRIVE LTC1148 SINGLE 5V REG 9 R4 22Ω C1 68µF C4 1000pF D2 MBRS140 14V AUXILIARY SUPPLY Q2 NDRIVE SENSE 20 D3 MBRS130T3 R1 100Ω + 15 SENSE– 14 C2 1000pF R3 18k Q3 VN7002 T1* 1.8T 30µH + C5 22µF VS VS AVPPOUT AEN0 R5 0.033Ω R2 100Ω + C3 220µF 5V OUTPUT TO “A” SLOT VPP PINS + 1µF AEN1 AVALID FROM “A” SLOT VCC PIN ASENSE LT1313 Q4 VN7002 BEN0 *LPE-6562-A026 DALE (605) 655-9301 AEN0 AEN1 AVALID BVPPOUT TO “B” SLOT VPP PINS + 1µF BEN1 BVALID BSENSE GND GND FROM “B” SLOT VCC PIN BEN0 BEN1 1313 TA04 BVALID NOTE: SEE LT1312 DATA SHEET APPLICATIONS SECTION FOR FURTHER DETAILS ON THIS CIRCUIT 10 LT1313 U PACKAGE DESCRIPTION Dimensions in inches (millimeters) unless otherwise noted.
