Product details
Overview
NIV2161MTTAG from onsemi is an automotive-grade ESD protection IC with integrated MOSFETs for short-to-battery and short-to-ground fault protection on high-speed differential data lines. It features 0.40 pF typical I/O-to-GND capacitance, ±8 kV IEC 61000-4-2 contact ESD rating, 16 V reverse working voltage, 29 V clamping voltage at 1 A, and 1.4 Ω typical RDS(on) at 4.5 V gate drive - enabling robust signal integrity in USB 2.0/3.0 and LVDS automotive interfaces.
For engineers reviewing the NIV2161MTTAG datasheet, pinout, applications, or equivalent options, this device serves as a flow-through, low-capacitance, AEC-Q101-qualified protection solution for differential pairs requiring simultaneous ESD, STB, and STG fault resilience without signal distortion.
Technical Context
The NIV2161MTTAG integrates dual-channel bidirectional ESD diodes and two matched N-channel MOSFETs per channel - one for D+ and one for D− - configured in a shared-source topology to enable active short-to-battery clamping and passive short-to-ground blocking. Its 1.0 V gate threshold voltage ensures compatibility with 3.3 V and 5 V logic-level control signals.
Operation includes three defined modes: normal linear conduction (signal pass-through), STB saturation-mode clamping (source voltage regulated near VGS − VTH), and STG reverse-diode blocking. The WDFN10 package's flow-through pinout (Pins 2/4 → host; Pins 7/9 → line; Pins 1/10 & 5/6 → sources) preserves differential impedance matching and minimizes stub length.

Equivalent & Alternatives
The following parts are listed as comparable options for similar ESD and short-circuit protection applications.
| Alternative Part | Technical Difference | Application Difference | Selection Advice |
|---|---|---|---|
| TPD2EUSB30DRYR | 0.5 pF capacitance; no integrated STB/STG MOSFETs - relies on external circuitry for battery-short protection | Limited to ESD-only use cases; unsuitable for automotive battery fault environments without added FETs | Select only if system already implements discrete short-circuit protection and requires lower-cost ESD-only solution |
| SP3203-04UTG | 0.35 pF capacitance; single-channel; no STB/STG capability; rated for ±12 kV ESD only | Designed for consumer USB ports - lacks AEC-Q101 qualification and automotive fault tolerance | Acceptable for non-automotive industrial USB hubs where STB/STG events are not expected |
Compared with TPD2EUSB30DRYR and SP3203-04UTG, the NIV2161MTTAG uniquely integrates all three protection functions (ESD, STB, STG) in a single AEC-Q101-qualified WDFN10 package - reducing layout complexity, eliminating external FETs, and ensuring compliance with ISO 10605 and OEM-specific short-circuit test plans without design iteration.

FAQ
What is the primary function of the NIV2161MTTAG in automotive signal chains?
The NIV2161MTTAG provides integrated ESD, short-to-battery (STB), and short-to-ground (STG) protection for high-speed differential data lines such as USB 2.0/3.0 and LVDS in automotive applications. It uses matched MOSFETs and bidirectional ESD diodes to protect transceivers without degrading signal integrity - a capability confirmed in its datasheet's electrical characteristics and application diagrams. The NIV2161MTTAG achieves this while maintaining 0.40 pF typical I/O capacitance and operating across −55 °C to +150 °C.
Does the NIV2161MTTAG require external gate drive circuitry?
No, the NIV2161MTTAG integrates internal gate control and requires only a single 5 V supply on Pin 3 to enable both D+ and D− channel MOSFETs. Its 1.0 V typical gate threshold voltage allows direct interfacing with standard 3.3 V or 5 V logic-level signals - eliminating need for level shifters or external drivers. This behavior is verified in the "Modes of Operation" section and electrical specs table of the NIV2161MTTAG datasheet.
How does the NIV2161MTTAG handle short-to-battery events?
During a short-to-battery event, the NIV2161MTTAG actively clamps the D+ and D− lines using its internal N-channel MOSFETs operating in saturation mode - limiting source voltage to approximately VGS − VTH and restricting current via port impedance. This mechanism is documented in the "Modes of Operation" section and supported by its 16 V reverse working voltage and 30 V VDSS rating - ensuring survival during 12–16 V battery faults without latch-up or degradation.
Is the NIV2161MTTAG compatible with USB 3.0 SuperSpeed data rates?
Yes, the NIV2161MTTAG supports USB 3.0 SuperSpeed (5 Gbps) due to its 5 GHz 3 dB bandwidth, 0.40 pF I/O capacitance, and flow-through pinout that preserves differential impedance. These parameters are explicitly specified in the "Electrical Characteristics" and "Application Information" sections of the NIV2161MTTAG datasheet - confirming signal transparency up to multi-gigabit frequencies without measurable jitter or attenuation.
What package type and footprint does the NIV2161MTTAG use?
The NIV2161MTTAG uses the WDFN10 package (3.5 mm × 2.0 mm, 0.675 mm pitch, Case 511CA), with an exposed thermal pad and Pb-free/RoHS-compliant construction. Its pinout is optimized for flow-through routing: Pins 2/4 connect host-side D+/D−, Pins 7/9 connect line-side D+/D−, and Pins 1/10 & 5/6 serve as common sources - all validated in the "Pin Configuration and Schematics" diagram of the NIV2161MTTAG datasheet.
