Nexperia USA Inc. NPIC6C4894PW-Q100J

Overview

NPIC6C4894PW-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified 12-stage serial-in/parallel-out shift register with open-drain extended-drain NMOS outputs (QP0–QP11), 33 V drain-source breakdown, 100 mA continuous per channel, and dual cascading serial outputs (QS1/QS2). It operates from −40 °C to +125 °C and drives automotive LED signage and fault indicators via latch-controlled data staging and output-enable gating.

For engineers reviewing the NPIC6C4894PW-Q100 datasheet, NPIC6C4894PW-Q100 pinout, NPIC6C4894PW-Q100 application, or NPIC6C4894PW-Q100 equivalent, key selection criteria include its 33 V clamped open-drain outputs, dual-edge serial cascade capability (QS1 on CP↑, QS2 on CP↓), 2.7 Ω typical R_DS(on) at 50 mA, 30 mJ avalanche energy rating, and automotive-grade thermal and ESD robustness (HBM >2500 V, CDM >1000 V).

Technical Context

This device integrates a 12-bit shift register followed by a storage latch stage, where data transfers from serial input (D) to parallel outputs only when latch enable (LE) is HIGH. The 12 open-drain EDNMOS outputs are individually controlled by OE: HIGH enables drive (sinking up to 100 mA continuously), LOW forces high-impedance OFF-state without affecting internal register states.

Cascading is supported via two asynchronous serial outputs: QS1 delivers shifted data on each positive clock edge for fast-rise-time systems, while QS2 provides the same data on the subsequent negative edge-enabling reliable daisy-chaining under slow-clock conditions. Integrated 33 V voltage clamps and 30 mJ avalanche energy handling protect against inductive transients from relays and solenoids.

FAQ

What is the maximum clock frequency supported by the NPIC6C4894PW-Q100?

The device supports a maximum serial clock frequency of 10 MHz under recommended operating conditions (V_CC = 4.5–5.5 V, T_amb = −40 °C to +125 °C). This is validated by propagation delay (t_pd = 5 ns from CP to QS1) and setup/hold timing (t_su/t_h = 20 ns each), enabling real-time LED pattern updates and responsive fault indication in automotive systems.

Can the NPIC6C4894PW-Q100 drive 24 V LED strings directly?

Yes-the 33 V drain-source breakdown voltage and integrated 33 V output clamping allow direct connection to 24 V LED strings when used with appropriate current-limiting resistors. Each QPn output sustains 100 mA continuous current, and the 30 mJ avalanche rating handles inductive transients without external protection components.

How does the dual serial output (QS1/QS2) improve cascade reliability?

QS1 delivers data on CP↑ for high-speed cascading with fast-rising clocks, while QS2 delivers the same data on CP↓ to accommodate slower clock edges. This dual-edge capability eliminates timing violations in long daisy chains-especially critical in automotive modules where PCB trace lengths and signal integrity vary across production batches.

Is the NPIC6C4894PW-Q100 pin-compatible with the SO20 version (NPIC6C4894D-Q100)?

No-while both share identical logic functionality and pin functions, the NPIC6C4894PW-Q100 uses TSSOP20 (SOT360-1) packaging with 0.65 mm lead pitch and 4.4 mm body width, whereas the NPIC6C4894D-Q100 uses SO20 (SOT163-1) with 1.27 mm pitch and 7.5 mm body width. Layout and reflow profiles differ significantly; direct PCB substitution is not possible.
