Nexperia USA Inc. LSF0101GW-Q100H

Overview

LSF0101GW-Q100 from Nexperia is a single-channel automotive-qualified bidirectional multi-voltage level translator supporting open-drain and push-pull interfaces, with ≤100 MHz up-translation and ≥100 MHz down-translation at 30 pF load, 5 V tolerant I/O pins, and no direction pin required. It enables voltage translation between 0.95 V–5.0 V domains in automotive infotainment and body control modules.

For engineers reviewing the LSF0101GW-Q100 datasheet, LSF0101GW-Q100 pinout, LSF0101GW-Q100 application, or LSF0101GW-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, flow-through TSSOP6 pinout, EN-controlled high-impedance state, and R_ON as low as 3 Ω at 1.8 V/3.3 V translation.

Technical Context

The LSF0101GW-Q100 implements an active-passive MOSFET-based translation architecture with dual reference voltage inputs (refA and refB) that independently set source and sink thresholds for bidirectional signal flow. Its enable-controlled gate drive eliminates external direction logic and supports hot insertion.

It operates across two distinct voltage domains simultaneously: one side referenced to refA (e.g., 1.8 V), the other to refB (e.g., 3.3 V), with propagation delays under 1.3 ns at 30 pF load and clamping protection compliant to HBM >2000 V and CDM >1000 V.

FAQ

What is the maximum capacitive load supported at 100 MHz translation?

The LSF0101GW-Q100 supports ≤100 MHz up-translation and ≥100 MHz down-translation only at ≤30 pF total load capacitance, as verified in Table 8 of the Rev. 2.1 datasheet. At 50 pF, maximum speed drops to 50 MHz in both directions. Exceeding 30 pF degrades timing margin and may cause setup/hold violations in I²C or MDIO protocols.

Can refA and refB be set to the same voltage?

Yes - refA and refB may be tied to identical voltages (e.g., both at 3.3 V) to enable bidirectional translation within the same domain, preserving signal integrity while providing EN-controlled isolation. This configuration is explicitly supported and maintains R_ON performance and ESD robustness per Section 11 static characteristics.

Does the device support true open-drain operation on both sides?

No - the LSF0101GW-Q100 supports open-drain *interfaces* (e.g., I²C pull-up buses) but uses active MOSFET switching internally. Both A1 and B1 pins exhibit low R_ON in the ON state and high-Z when EN = LOW. True open-drain behavior is emulated via external pull-ups on either side, as confirmed in Figure 2 test circuit and Section 1 functional description.

Is there a minimum voltage differential required between refA and refB?

No minimum differential is specified - refA and refB may differ by as little as 100 mV (e.g., 1.80 V and 1.90 V) or span full range (0.95 V ↔ 5.0 V). The device's adaptive threshold circuitry accommodates any valid combination within datasheet limits, validated across all pairs listed in Section 2 features (e.g., 0.95 V ↔ 1.8 V, 3.3 V ↔ 5.0 V).
