R FE T PI5101 in a full function Active ORing DS(on) Remove power and use caution when connecting and solution. It is not designed to be installed in end-use disconnecting test probes and interface lines to avoid equipment. inadvertent short circuits and contact with hot surfaces. Please read this document before setting up the PI5101- When testing electronic products always use approved EVAL1 Evaluation Board and refer to the PI2001 and safety glasses. Follow good laboratory practice and PI5101 product datasheets for device specifications, procedures. functional description and characteristics. Introduction The PI5101-EVAL1 allows the user to test the basic applications requiring up to 60A. This evaluation board is principles and operational characteristics low voltage high intended as an easy and simple way to test the electrical current Active ORing function in a redundant power and thermal performance of the PI5101 ultra-low R DS(on) architecture, while also experiencing the benefits and the MOSFET and PI2001 Active ORing controller. value of the PI5101 ultra-low R MOSFET. The PI5101- DS(on) Both dynamic and steady state testing of the PI5101 and EVAL1 evaluation board is configured to receive two the PI2001 can be completed on the PI5101-EVAL1 independent power source inputs, per a typical redundant evaluation board, in addition to using the key features of power architecture, through two Active ORing channels the product. Dynamic testing can be completed under a that are combined to form a redundant power output. variety of system level fault conditions to check for Each channel contains a PI2001 controller and PI5101 response time to faults.

The PI5101 offers unprecedented figure- of-merits for DC and switching application including R x Q , gate resistance (R ) and package inductance DS(on) G G (L ) outperforming conventional Trench MOSFETs and DS enabling very low loss operation. Using the PI2001 controller with the PI5101 ultra-low R N-channel MOSFET provides very high efficiency DS(on) and low power loss during steady state operation. The PI2001 controller provides an active low fault flag output to the system during excessive forward current, light load, reverse current, over-voltage, under-voltage, and Terminals Maximum Rating over-temperature fault conditions. The under-voltage Vin1, Vin2, 5V/60A and over-voltage thresholds are programmable via an external resistor divider. Vout 5V/60A The PI5101 LGA package is fully compatible with industry 1, 2 -0.3V to 17.3V / 10mA standard SMT assembly processes. Vaux1, Vaux2 -0.3V to 17.3V / 40mA Figure 1: PI5101-EVAL1 Evaluation Board (1.8 x 2.8) Terminal Description Vin1 Power source Input 1 or bus input designed to accommodate up to 60A continuous current. Vin2 Power source Input 2 or bus input designed to accommodate up to 60A continuous current. 1 PI2001 (U1) Fault pin: Monitors U1 fault conditions. 2 PI2001 (U2) Fault pin: Monitors U2 fault conditions. Auxiliary Input Voltage 1: supply PI2001 VC power. Vaux1 should be equal to Vin1 plus 5 V or higher. See details in Vaux1 Auxiliary Power Supply (Vaux) section of the PI2001 data sheet. Auxiliary Input Voltage 2: supply PI2001 VC power. Vaux2 should be equal to Vin2 plus 5 V or higher. See details in Vaux2 Auxiliary Power Supply (Vaux) section of the PI2001 data sheet. Vout Output M1 and M2 MOSFETs drain connection: connect to the load high side. Return Connection: Ten Gnd connections are available and are connected to a common point, the Ground plane. Input Gnd supplies Vin1, Vin2, Vaux1, Vaux2 and the output load at Vout should all be connected to their respective local Gnd connection.
