Nexperia USA Inc. NEVB-NID5100UL

Overview

NEVB-NID5100UL from Nexperia is a two-layer evaluation board featuring two NID5100 ideal diodes and one external PMOS transistor (NXV65UPR), designed to validate OR-ing, priority OR-ing, reverse polarity protection, and reverse current blocking in low-voltage power systems. It supports 1.2 V to 5.5 V input, 1.5 A continuous current per channel, and includes USB-C inputs, jumper-configurable use cases, and full pin access.

For engineers reviewing the NEVB-NID5100UL datasheet, NEVB-NID5100UL pinout, NEVB-NID5100UL application, or NEVB-NID5100UL equivalent, this board enables rapid validation of ideal diode behavior across dual-supply redundancy, microcontroller-driven priority selection, and polarity-reversal fault tolerance - critical for portable, battery-powered, and USB-C powered embedded systems.

Technical Context

The board implements two independent NID5100 ideal diodes - each integrating a 1.5 A P-channel MOSFET with active gate control for <30 mV forward voltage drop and automatic reverse current blocking. Input voltage range is strictly 1.2 V–5.5 V, with quiescent current below 1 µA per device.

Five configurable use cases are supported via physical jumpers and a DPDT switch: dual OR-ing, priority OR-ing (with ST/EN signal chaining), reverse polarity protection (via SW1 inversion of VIN1), reverse current blocking verification, and OR-ing with external PMOS (Q1). All test points and supply nodes are exposed for oscilloscope probing and lab instrumentation.

FAQ

What is the default configuration of the NEVB-NID5100UL?

The board ships configured for dual OR-ing: both NID5100 devices (U1 and U2) are enabled via jumpers J4 and J5 (pins 2–3), and outputs VOUT1 and VOUT2 are paralleled via jumper J6. This allows immediate validation of automatic source selection between two supplies - e.g., USB-C ports delivering 5 V and 3.3 V - without any rework.

How do I verify reverse polarity protection on this board?

Set SW1 to reverse polarity mode (positions 2–3), enable U1 via jumper J4 (2–3), and apply voltage to J1 or J2. The output VOUT1 remains off while the red LED indicates input presence. Oscilloscope traces (Fig. 5–6 in UM90040) confirm zero output conduction and no latch-up - validating that the NID5100 blocks reverse-biased input without damage or leakage.

Can the NEVB-NID5100UL evaluate priority OR-ing with a microcontroller?

Yes. Connect a microcontroller GPIO to J4 pin 2–3 to drive U1's EN pin. U2's EN is tied to U1's ST output via J5 (1–2), inverted by R2. When U1 is enabled, its ST goes high, disabling U2 - establishing hardware-enforced priority. Load current routing is confirmed via PRIO signal monitoring and load-step response on VOUT1/VOUT2 under 47 Ω loading (Fig. 9–10).

Does the board support testing with an external PMOS transistor?

Yes. Install jumper J11 (2–3) to connect U2's ST to Q1's gate, and jumper J12 (2–3) to enable VOUT2–VOUT3 OR-ing. With U2 enabled (J5: 2–3), Q1 conducts when VIN3 exceeds VIN2 + V_TH (~1.2 V), and U2's reverse-blocking action pulls ST low to fully enhance the PMOS. Fig. 11–12 shows clean turn-on and hold-off behavior during 3.3 V/5 V transitions.
