Product details

Overview

NPIC6C4894D-Q100 from Nexperia is a 12-stage automotive-qualified serial shift register with open-drain extended-drain NMOS outputs (QP0–QP11), latch enable (LE), output enable (OE), and dual serial outputs (QS1/QS2) for cascading. It operates from −40 °C to +125 °C, delivers 100 mA continuous per output, features 33 V output clamping, and supports up to 10 MHz clock frequency-used in LED signage and fault status indicators.

For engineers reviewing the NPIC6C4894D-Q100 datasheet, NPIC6C4894D-Q100 pinout, NPIC6C4894D-Q100 application, or NPIC6C4894D-Q100 equivalent, key selection criteria include AEC-Q100 Grade 1 qualification, 12-bit power driver capability, dual-cascade serial outputs (QS1/QS2), R_DS(on) ≤ 10 Ω at 100 mA, and integrated avalanche energy protection (30 mJ).

Technical Context

This device implements a synchronous 12-bit serial-in/parallel-out shift register architecture with separate storage latches. Data shifts on positive CP edges and transfers to the storage register when LE is HIGH; outputs drive external loads only when OE is HIGH, entering high-impedance OFF-state otherwise.

QS1 provides serial data on positive CP edges for fast-rise-time cascading; QS2 delivers the same data on the subsequent negative CP edge for slow-rise-time systems. Each QPn output integrates an extended-drain NMOS transistor rated for 33 V V_DS, 100 mA continuous current, and 250 mA pulsed current, with built-in voltage clamping and 30 mJ non-repetitive avalanche energy capability.

Key Specifications

Parameter	Value and Actual Design Meaning
Output count	12 parallel open-drain outputs (QP0–QP11) for independent load control
Max clock frequency	10 MHz - enables high-speed serial data chaining across multiple devices
Continuous output current	100 mA per channel - drives LEDs, relays, or solenoids without external buffers
Output clamping voltage	33 V - protects against inductive transients in automotive relay/solenoid switching
Avalanche energy	30 mJ (single-pulse) - sustains inductive kickback without failure in power-driver applications
Operating temperature	−40 °C to +125 °C - meets AEC-Q100 Grade 1 for under-hood automotive use
R_DS(on)	2.8 Ω typical at 100 mA, V_CC = 4.5 V - minimizes conduction loss and self-heating

Pinout & Package

NPIC6C4894D-Q100 uses the SO20 plastic small outline package (SOT163-1), 20-pin, 7.5 mm body width, with gull-wing leads and standard JEDEC footprint.

Pin/Terminal	Circuit Role	Design Meaning
LE (Pin 1)	Latch enable input	Transfers shifted data from shift register to storage latch on HIGH; controls timing of parallel output update
D (Pin 2)	Serial data input	Accepts 1-bit serial stream synchronized to CP rising edge
CP (Pin 3)	Clock input	Positive-edge-triggered shift clock; also gates QS1/QS2 timing behavior
QP0–QP11 (Pins 4–9, 13–18)	Parallel open-drain outputs	12 individually controllable extended-drain NMOS drivers; sink current only, require external pull-up
GND (Pin 10)	Ground reference	Common return path for all internal logic and output current paths
QS1 (Pin 11)	Fast-cascade serial output	Outputs shifted data on CP rising edge - used with fast-rising clocks
QS2 (Pin 12)	Slow-cascade serial output	Outputs same data on CP falling edge - accommodates slow-rising clocks in daisy-chain
OE (Pin 19)	Output enable	Active-HIGH control: disables all QPn outputs into high-Z state without affecting register contents
V_CC (Pin 20)	Supply voltage	4.5–5.5 V nominal operation; powers logic core and gate drivers

Key Features

Feature	Design Value
AEC-Q100 Grade 1 qualification	Validated for automotive use across −40 °C to +125 °C ambient, including lifetime reliability testing
Dual-cascade serial outputs	QS1 (positive-edge) and QS2 (negative-edge) enable robust daisy-chaining under varying clock slew rates
Integrated transient protection	On-die clamping diodes limit QPn drain voltage to 33 V, eliminating need for external TVS in many relay/LED drivers
High-energy avalanche tolerance	30 mJ single-pulse rating allows safe interruption of inductive loads like solenoids without derating
Low R_DS(on) and leakage	2.8 Ω typical at 100 mA; <0.3 µA OFF-state leakage - reduces thermal stress and standby power

Applications

LED Signage

Graphic Status Panel

Use Scenario: Driving rows/columns of red/green/blue LEDs in outdoor vehicle message signs.

IC Role / Device Role / Timing Role: 12-bit serial-to-parallel power driver; receives SPI-like data via D/CP/LE and sinks LED current through QPn outputs.

Use Value: Eliminates discrete MOSFET arrays; 100 mA per channel supports high-brightness LEDs; 33 V clamping handles LED string open-circuit transients.

Use Scenario: Backlighting and segment control in dashboard graphic displays with multi-color indicators.

IC Role / Device Role / Timing Role: Cascadable shift register providing individual anode/cathode control for segmented icons and warning glyphs.

Use Value: QS1/QS2 flexibility ensures reliable data propagation across long PCB traces; AEC-Q100 qualification guarantees display uptime in harsh thermal cycles.

Fault Status Indicator

Automotive Relay Driver

Use Scenario: Illuminating MIL (Malfunction Indicator Lamp), brake warning, or airbag fault lights in instrument clusters.

IC Role / Device Role / Timing Role: Latched output driver translating ECU diagnostic codes into visible lamp states via QPn outputs.

Use Value: OE-controlled high-Z shutdown isolates lamps during system reset; 125 °C operation prevents thermal shutdown during prolonged engine-off diagnostics.

Use Scenario: Directly switching 12 V automotive relays (e.g., HVAC, lighting, wiper modules) without external flyback diodes.

IC Role / Device Role / Timing Role: Power-level shift register managing coil energization timing and polarity via QPn open-drain outputs.

Use Value: 30 mJ avalanche energy absorbs relay coil collapse energy; integrated clamping avoids board-level component count increase.

Equivalent & Alternatives

The following parts are listed as comparable options for similar 12-bit power shift register applications.

Alternative Part	Technical Difference	Application Difference	Selection Advice
TPIC6B595QPWRQ1	8-bit output count; 150 mA per channel; no QS2 output; identical AEC-Q100 Grade 1 rating	Requires two devices for 12-bit coverage; higher per-channel current but less cascade flexibility	Select when higher per-output current is prioritized over bit count and dual-cascade timing
ULN2803AQDRQ1	8-channel Darlington array; no shift register; 500 mA peak per channel; no serial interface	Needs external shift logic (e.g., 74HC595); larger footprint; higher V_CE(sat) causes more heat	Select when simple parallel control suffices and discrete logic integration is acceptable

Compared with TPIC6B595QPWRQ1 and ULN2803AQDRQ1, the NPIC6C4894D-Q100 uniquely combines 12-bit serial control, dual-edge cascading, and automotive-grade avalanche robustness in a single SO20 package-reducing BOM count and layout complexity for LED and relay driver subsystems.

FAQ

What is the maximum allowable V_DS across QPn outputs?

The absolute maximum drain-source voltage is +33 V, verified per IEC 60134 limiting values. This clamping level is enforced by integrated on-die protection diodes and applies continuously-not just during transients-making it suitable for 24 V automotive loads with margin.

Can NPIC6C4894D-Q100 drive LEDs directly without external current-limiting resistors?

No. While each QPn output can sink up to 100 mA continuously, external series resistors are required to set LED current and ensure stable forward voltage drop. The device does not regulate current; it functions as a controlled switch, so resistor value must be calculated based on V_CC, LED V_F, and desired I_F.

How does QS1 differ from QS2 in cascaded configurations?

QS1 outputs data on the same positive CP edge that loads it into the final shift register stage, enabling minimal latency in high-speed chains. QS2 outputs the identical data one half-cycle later-on the subsequent negative CP edge-providing setup time margin for slower clock edges or longer inter-device trace delays, improving timing margin in large daisy-chains.

Is OE pin functionality compatible with hot-swap or partial system power-down?

Yes. Asserting OE LOW places all QPn outputs in high-impedance OFF-state without altering internal register contents or affecting LE/CP/D operation. This allows dynamic load isolation during power sequencing or fault recovery while preserving shift register state-critical for fail-safe automotive subsystems.
