Nexperia USA Inc. NPIC6C595BQ,115

Overview

NPIC6C595BQ,115 from Nexperia is an 8-bit serial-in/parallel-out shift register with open-drain extended-drain NMOS outputs, separate shift and storage clocks (SHCP/STCP), asynchronous master reset (MR), and active-low output enable (OE). It delivers 100 mA continuous current per channel, 33 V output clamping, and 30 mJ avalanche energy rating - designed for driving LEDs, relays, and solenoids in industrial status panels and fault indicators.

For engineers reviewing the NPIC6C595BQ,115 datasheet, NPIC6C595BQ,115 pinout, NPIC6C595BQ,115 application, or NPIC6C595BQ,115 equivalent, key selection criteria include its DHVQFN16 thermal-enhanced package, 10 MHz max shift clock frequency, 3.1 Ω typical R_DS(on) at 100 mA, and integrated voltage clamping for inductive load protection.

Technical Context

The device implements dual-register architecture: an 8-stage shift register accepting serial data via DS and clocked by SHCP, and a parallel-accessible storage register loaded on STCP edges. Output drivers are power EDNMOS transistors with source tied internally to GND and drain terminals (Q0–Q7) rated for 33 V and 100 mA continuous.

Operation is fully asynchronous between shift and storage domains; cascading is enabled via Q7S serial output. OE controls high-impedance state without affecting register contents, while MR independently clears both registers. All logic inputs tolerate 5.5 V and operate across –40 °C to +125 °C.

FAQ

What is the maximum safe voltage that can be applied to the Q0–Q7 outputs?

The Q0–Q7 outputs are rated for 33 V drain-source breakdown voltage (V_(BR)DSS) with a guaranteed minimum of 33 V and typical value of 37 V. Continuous operation above 33 V risks permanent damage; external clamping is unnecessary due to integrated protection, but load supply must not exceed 33 V.

Can NPIC6C595BQ,115 drive multiple LEDs in series from a 24 V rail?

No - the open-drain outputs sink current to GND and require the LED anode to be connected to a positive supply. To drive LEDs in series, the supply voltage must exceed the combined forward voltage (e.g., 4 × 3.2 V = 12.8 V), and the cathode chain connects to Qn. A 24 V rail is compatible only if total LED V_F < 24 V and current-limiting resistor is sized for 100 mA.

How does the DHVQFN16 package improve thermal performance over SO16 or TSSOP16?

The DHVQFN16 (SOT763-1) package provides 1825 mW total power dissipation at 25 °C - more than double the SO16 (800 mW) and TSSOP16 (725 mW) variants - due to its exposed thermal pad and low thermal resistance (11.2 mW/K derating above 106 °C), enabling sustained 100 mA per channel operation in compact designs.

Is the MR (master reset) pin synchronous or asynchronous?

The MR pin is asynchronous and active-low: asserting MR immediately clears both the shift register and storage register to zero, regardless of SHCP or STCP state. The reset is not edge-triggered and takes effect within nanoseconds of MR falling below V_IL, enabling immediate fault recovery without clock dependency.
