The LM73100 Integrated Ideal Diode Evaluation Module allows reference circuit evaluation of Texas Instruments (TI) LM73100 Ideal Diode. The LM73100 device is 2.7-V to 23-V, 5.5-A ideal diode power switch with integrated 28-mΩ FET, always ON reverse current blocking, programmable undervoltage and overvoltage, adjustable output slew rate control, overtemperature protection and power good indication with programmable threshold.

LM73100EVM Integrated Ideal Diode evaluation board features include:

• 2.7 V to 23 V (typ), 5.5 A operation
• Programmable output voltage slew rate control
• Programmable overvoltage lockout threshold

• LED status indication for Power Good output

• Onboard Schottky diode at output prevents negative spike during overcurrent faults

• TVS diode for input transient protection

This EVM can be use on the following applications:

• Power MUX and power ORing
• Adapter input protection
• Monitors and docks
• Patient monitors
• Smart speakers
• Headphones
• Building automation

The LM73100EVM Integrated Ideal Diode Evaluation Board enables evaluation of LM73100 Integrated Ideal Diode device through two channels. The input power is applied at connectors J5 (for Channel1) and J10 (for Channel2) while J1(for Channel1) and J7 (for Channel2) provides the output connection to the load; refer to the schematic in Figure 3-1, and EVM test setup in Figure 5-1.

S1 and S2 allows U1 and U2 to be RESET or disabled respectively. A power good (PG) indicator is provided by D6 (for Channel1) and D11 (for Channel2). Scaled device current can be monitored at TP15 with a scale factor of 0.22 V/A.
