Nexperia USA Inc. NPIC6C596BQ-Q100,1

Overview

NPIC6C596BQ-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified 8-bit serial-in/parallel-out shift register with open-drain extended-drain NMOS (EDNMOS) outputs, dual independent clocks (SHCP and STCP), asynchronous master reset (MR), and output enable (OE). It delivers 100 mA continuous current per channel, 33 V output clamping, and 30 mJ avalanche energy - designed for automotive LED signage, fault indicators, and relay/solenoid drivers.

For engineers reviewing the NPIC6C596BQ-Q100 datasheet, NPIC6C596BQ-Q100 pinout, NPIC6C596BQ-Q100 application, or NPIC6C596BQ-Q100 equivalent, key selection criteria include its DHVQFN16 package with side-wettable flanks, cascading support via Q7S, 5 V operation, -40 °C to +125 °C automotive temperature range, and integrated inductive transient protection for power-switching reliability.

Technical Context

The device implements two synchronized but independent register stages: an 8-bit shift register clocked by SHCP (LOW-to-HIGH edge) and a storage register clocked by STCP (LOW-to-HIGH edge), enabling precise timing control between data latching and output driving. Cascading is enhanced by Q7S output clocked on the falling edge of SHCP to extend hold time.

Each of the eight open-drain EDNMOS outputs features 33 V drain-source breakdown voltage, 100 mA continuous current rating, and integrated voltage clamps that suppress inductive kickback - eliminating external flyback diodes in relay and solenoid drive applications.

FAQ

What is the maximum recommended clock frequency for NPIC6C596BQ-Q100?

The maximum shift clock (SHCP) frequency is 10 MHz under recommended operating conditions (VCC = 5 V, ID = 75 mA, Tamb = 25 °C). This limit accounts for propagation delay (tpd ≤ 5 ns), setup/hold timing margins, and cascaded operation where Q7S must settle before the next stage samples. At elevated temperatures or higher load currents, derating is advised to maintain timing integrity.

Can NPIC6C596BQ-Q100 drive 24 V LED strings directly?

Yes - its 33 V output clamping voltage and 100 mA continuous current rating allow direct connection to 24 V LED strings with appropriate current-limiting resistors. The integrated clamp prevents voltage overshoot during turn-off, eliminating external flyback diodes. However, total power dissipation must remain within the DHVQFN16 package limit of 1825 mW at 25 °C (derating to 365 mW at 125 °C).

How does the MR (master reset) pin interact with OE (output enable)?

MR asynchronously clears both the shift and storage registers to zero, forcing all Qn outputs to high-impedance regardless of OE state. OE operates independently: when HIGH, it overrides register contents and forces all outputs OFF; when LOW, outputs reflect the storage register state. MR does not affect OE's logic level or function - the two controls operate orthogonally for fail-safe initialization and dynamic output gating.

Is thermal pad connection mandatory for NPIC6C596BQ-Q100?

Yes - the exposed thermal pad (pin 1 index area) must be soldered to a PCB ground plane with adequate copper area. It serves as the primary thermal path and electrical ground return for all eight EDNMOS outputs. Leaving it unconnected violates the SOT763-1 mechanical specification and risks thermal runaway under full-load operation, especially at high ambient temperatures.
