Nexperia USA Inc. NID5100GWH

Overview

NID5100GWH from Nexperia is an integrated ideal diode IC designed for low-voltage power OR-ing and reverse-polarity protection in space-constrained systems. It replaces Schottky diodes with a regulated forward drop of 31 mV (typ) at 10 mA, supports 1.2 V to 5.5 V input, delivers up to 1.5 A continuous current, and integrates active-low EN control and open-drain ST status indication - deployed in smart meters and building automation power rails.

For engineers reviewing the NID5100GWH datasheet, NID5100GWH pinout, NID5100GWH application, or NID5100GWH equivalent, key selection criteria include its 31 mV regulated forward voltage, -40 °C to +125 °C operating range, TSSOP6 (SOT363-2) package footprint, 240 nA quiescent current, and dual-mode operation (forward regulation vs. body-diode conduction) enabled by the EN pin.

Technical Context

The NID5100GWH implements a gate-regulated PMOS architecture with internal amplifier feedback to maintain precise VREG = VIN − VOUT ≈ 31 mV at light loads, transitioning to R_ON-dominated drop (115 mΩ typ) under 500 mA. Its reverse-current blocking (RCB) uses dual mechanisms: slow-response VREG loop saturation and fast-trip comparator activation at VRCB_R = 30.5 mV (typ) to disable the PMOS within 10–220 µs during polarity reversal.

Reverse-polarity protection operates autonomously regardless of EN state, blocking −6 V absolute max input with zero reliance on external components. The ST pin provides real-time conduction status: high-impedance when regulating forward current, actively pulled low during disable or reverse-bias conditions - enabling direct MCU monitoring or cascaded PMOS control in hybrid OR-ing topologies.

FAQ

What is the maximum reverse voltage the NID5100GWH can withstand without damage?

The NID5100GWH has an absolute maximum rated reverse input voltage of −6.0 V, verified per IEC 60134 limiting values. This rating applies regardless of EN pin state and enables robust protection against accidental battery misinsertion or reversed universal adapter connections in end equipment.

Can the ST pin drive an external PMOS directly without a level shifter?

Yes - the ST pin is open-drain with VOL ≤ 0.1 V at 1 mA sink current and supports rail-to-rail voltage compatibility up to 5.5 V. When used to control an external PMOS gate, a single pull-up resistor to OUT or V_IN suffices; no level shifter is needed for common 3.3 V or 5 V logic domains.

How does the NID5100GWH behave during fast input voltage transients like ESD or load dump?

During fast transients, the integrated RCB comparator responds within 10 µs (t_OFF) when V_OUT − V_IN exceeds 30.5 mV, disabling the PMOS before significant reverse current flows. Combined with ±2 kV HBM and ±500 V CDM ESD ratings, this provides system-level immunity without external TVS diodes in most Class B environments.

Is the n.c. pin (Pin 4) required to be connected for functional reliability?

Pin 4 is not internally connected and carries no electrical function. However, Nexperia specifies it must be soldered to the PCB pad for mechanical integrity - leaving it unconnected risks package cracking or solder joint fatigue under thermal cycling or board flexure in field-deployed equipment.
