Two external N-Channel MOSFETs are driven to distribute power while providing load fault isolation. At turn-on, the gate of each external N-Channel MOSFET is charged with a 10A current source. Capacitors on each gate (see the Typical Application Diagram), create a programmable ramp (soft turn-on) to control inrush currents. A built in charge pump supplies the gate drive for the 12V supply N-Channel MOSFET switch. Over current protection is facilitated by two external current sense resistors. When the current through either resistor exceeds the user programmed value the N-Channel MOSFETs are latched off by the HIP1013. The controller is reset by a rising edge on either PWRON pin. • HOT SWAP Dual Power Distribution Control for +5V and +12V or +5V and +3.3V • Provides Fault Isolation • Charge Pump Allows the Use of N-Channel MOSFETs • Redundant Power On Controls • Power Good and Over Current Latch Indicators • Adjustable Turn-On Ramp • Protection During Turn-On • Pb-free Available Applications • Power Distribution Control • Hot Plug™ Components Typical Application Diagram Choosing the voltage selection mode the HIP1013 controls either +12V/5V or +3.3V/+5V supplies.

SYMBOL FUNCTION 1 12VS 12V Source Connect to source of associated external N-Channel MOSFET switch to sense output voltage. 2 12VG 12V Gate Connect to the gate of associated N-Channel MOSFET switch. A capacitor from this node to ground sets the turn-on ramp. At turn-on this capacitor will be charged to 17.4V by a 10A current source when in 5V/12V mode of operation, otherwise capacitor will be charged to 11.4V. 3 VDD Chip Supply Connect to 12V supply. This can be either connected directly to the +12V rail supplying the load voltage or to a dedicated VDD +12V supply. 4 MODE/ PWRON1 Power ON/ Reset invokes 3.3V operation when shorted to VDD , Pin 3. 5 PWRON2 Power ON/Reset PWRON1 and PWRON2 are used to turn-on and reset the chip. Both outputs turn-on when either pin is driven low. After an over current limit fault, the chip is reset by the rising edge of a reset signal applied to either PWRON pin. Each input has 100A pull up capability which is compatible with 3V and 5V open drain and standard logic. PWRON1 is also used to invoke 3.3V control operation in preference to +12V control. By tying pin 4 to pin 3 the charge pump is disabled and the UV threshold also shifts to 2.8V. 6 5VG 5V Gate Connect to the gate of the external 5V N-Channel MOSFET. A capacitor from this node to ground sets the turn-on ramp. At turn-on this capacitor will be charged to 11.4V by a 10A current source. 7 5VS 5V Source Connect to the source side of 5V external N-Channel MOSFET switch to sense output voltage. 8 5VISEN 5V Current Sense Connect to the load side of the 5V sense resistor to measure the voltage drop across this resistor between 5VS and 5VISEN pins. 9 PGOOD Power Good Indicator PGOOD is driven by an open drain N-Channel MOSFET.

OC VOLTAGE THRESHOLD WITH = RILIM 10k HIP1013 Description and Operation The HIP1013 offers the designer a cost efficient 5V and 12V true hot plug controller. This device drives two external N-Channel MOSFET switches and uses a charge pump to provide 17V to drive the gate of the 12V supply switch. The HIP1013 features Over Current (OC) programing with a single external resistor, RILIM and during turn-on, the gate capacitor of each external N-Channel MOSFET is charged with a 10A current source. These capacitors create a programmable ramp (soft turn-on). Upon initial power up, the HIP1013 can either isolate the voltage supply from the load by holding the external N-Channel MOSFET switches off or apply the supply rail voltage directly to the load for true hot swap capability. In either case the HIP1013 turns on in a soft start mode protecting the supply rail from sudden current loading. The load currents pass through two external current sense resistors. When the voltage across either resistor exceeds the user programmed Over Current (OC) voltage threshold value, (see Table 1) the HIP1013 controller turns both N-Channel MOSFETs off in 2s. TABLE 1. RILIM RESISTOR NOMINAL OC VTH 15K 150mv 10K 100mV 7.5K 75mV 4.99K 50mV NOTE: Nominal OC Vth = RILIM x 10 A The HIP1013 is reset by a rising edge on either PWRON pin and is turned on by either PWRON pin being driven low. The HIP1013 can control either +12V/5V or +3.3V/+5V supplies. Tying the PWRON1 pin to VDD , invokes the +3.3V/+5V voltage mode. In this mode, the external charge pump capacitor is not needed and CPUMP, pin 11 is also tied 6 10.0 FIGURE 8. POWER ON RESET VOLTAGE THRESHOLD directly to VDD . Upon any OC or Under Voltage (UV) condition the PGOOD fault indicating signal will pull low when tied high through a resistor to the logic supply. 80 HIP1013 HIP1013 Application Considerations There is no unique and specific HIP1013 application evaluation board. Since the HIP1013 is pin compatible with the HIP1012 device, you can substitute a HIP1013 for the existing HIP1012 in either of the HIP1012EVAl1 or EVAL2 boards. Otherwise contact your Intersil Corporation sales office and an already modified board will be provided. Although pin compatible to the HIP1012, the HIP1013 is a less featured dual power supply distribution controller and does not include programmable current limiting regulation and delay time to latch off. Random resets can also occur if the HIP1013 (PINS 8 and 14) sense pins are pulled below ground when turning off a highly inductive load. Place a large load capacitor (10-50F) on the output to eliminate unintended resets. Physical layout of RSENSE resistors is critical to avoid the possibility of false over current occurrences. Ideally trace routing between the RSENSE resistors and the HIP1013 VS and VISEN pins are direct and as short as possible with zero current in the sense lines.
