Nexperia USA Inc. NXS0101GW-Q100H

Overview

NXS0101GW-Q100 from Nexperia is a 1-bit automotive-qualified dual-supply translating transceiver with auto-direction sensing and open-drain I/O, enabling bidirectional level translation between 1.65 V–3.6 V (VCC(A)) and 2.3 V–5.5 V (VCC(B)) domains. It features integrated 10 kΩ pull-ups per port, IOFF partial power-down protection, and supports up to 24 Mbps data rate in push-pull mode. It is deployed in I²C and 1-wire interfaces between mixed-voltage subsystems in automotive infotainment and body control modules.

For engineers reviewing the NXS0101GW-Q100 datasheet, NXS0101GW-Q100 pinout, NXS0101GW-Q100 application, or NXS0101GW-Q100 equivalent, this page delivers verified functional architecture, validated voltage translation boundaries, confirmed AEC-Q100 Grade 1 qualification, and real-world timing behavior under -40 °C to +125 °C operation - all critical for automotive signal integrity and BOM continuity planning.

Technical Context

The NXS0101GW-Q100 implements a switch-type voltage translator using an N-channel pass-gate transistor biased ~1 V_TH above VCC(A), enabling passive bidirectional conduction without external direction control. Its dual one-shot edge-accelerator circuitry detects rising edges at ~0.5×VCCI and temporarily activates PMOS transistors (T1/T2) to reduce output impedance to 50–70 Ω during transitions, accelerating low-to-high slew rates.

Internal 10 kΩ pull-up resistors on both A and B ports eliminate external biasing for open-drain protocols like I²C; OE is active-HIGH referenced to VCC(A) and forces high-impedance OFF-state when LOW. The IOFF circuit ensures <±2 μA leakage when either supply is powered down, preventing backflow current and meeting AEC-Q100 partial power-down requirements.

FAQ

What is the maximum allowable voltage difference between VCC(A) and VCC(B)?

VCC(A) must always be ≤ VCC(B) per datasheet Section 8 and Table 4. No absolute voltage difference limit is specified, but VCC(A) = 3.6 V and VCC(B) = 2.3 V violates the requirement and may cause malfunction. Valid combinations include VCC(A) = 1.8 V / VCC(B) = 3.3 V or VCC(A) = 3.3 V / VCC(B) = 5.0 V - both tested and guaranteed across -40 °C to +125 °C.

Can the NXS0101GW-Q100 be used with push-pull drivers?

Yes, but with caveats: the device supports push-pull inputs per Section 13.3, yet its architecture is optimized for open-drain protocols like I²C. When driven by push-pull sources, ensure output impedance <50 Ω to meet 24 Mbps timing specs; for dedicated push-pull translation, Nexperia recommends the NXB0101GW-Q100 instead.

How does the IOFF circuit behave during asymmetric power sequencing?

IOFF activates automatically when either VCC(A) or VCC(B) drops below operational threshold, disabling outputs and limiting leakage to <±2 μA (Section 11, Table 9). During power-up, no sequencing is required - VCC(A) may ramp before or after VCC(B) without damage, per Section 13.5.

Are the internal pull-up resistors active when OE = LOW?

No. Section 13.7 explicitly states: "When OE goes LOW the internal pull-ups of the NXS0101-Q100 are disabled." This ensures true high-impedance isolation - critical for bus arbitration and multi-master I²C systems where floating nodes must be avoided during standby.
