Nexperia USA Inc. NPIC6C596BQ,115

Overview

NPIC6C596BQ,115 from Nexperia is an 8-bit serial-in/parallel-out shift register with separate shift and storage register clocks, open-drain extended-drain NMOS (EDNMOS) outputs rated for 33 V and 100 mA continuous current per channel, asynchronous master reset (MR), and active-low output enable (OE). It drives moderate-power loads such as LED signage, relay coils, and solenoids in industrial control panels and fault indicator systems.

For engineers reviewing the NPIC6C596BQ,115 datasheet, NPIC6C596BQ,115 pinout, NPIC6C596BQ,115 application, or NPIC6C596BQ,115 equivalent, key selection criteria include its 33 V output clamping voltage, 30 mJ avalanche energy rating, DHVQFN16 thermal-enhanced package, cascading support via Q7S, and operation across –40 °C to +125 °C.

Technical Context

The device implements dual-clock architecture: SHCP controls data shifting through the 8-stage shift register, while STCP latches data into the independent 8-bit storage register-enabling precise timing separation between data loading and output update. The Q7S serial output is edge-aligned to the falling edge of SHCP to extend hold time in multi-stage daisy-chained configurations.

All eight outputs are power EDNMOS transistors with integrated voltage clamps, supporting 33 V drain-source breakdown and 250 mA pulsed current. OE operates independently of register state, placing outputs in high-impedance OFF-state without affecting internal data retention or clocking behavior.

FAQ

Can NPIC6C596BQ,115 drive 24 V LED strings directly?

Yes-it supports up to 33 V on its open-drain outputs and delivers 100 mA continuous per channel. When used with a 24 V supply and appropriate current-limiting resistors on the high-side, it directly sinks LED string current. Its 30 mJ avalanche rating also handles transient overvoltage from LED line surges without external protection.

What is the purpose of the separate SHCP and STCP clocks?

SHCP shifts data serially into the 8-bit shift register, while STCP transfers that data in parallel to the output storage register. This separation prevents glitches during data loading: outputs remain stable until STCP triggers, enabling clean, simultaneous updates across all 8 channels-critical for flicker-free LED displays or coordinated relay switching.

Is the thermal pad on the DHVQFN16 package required to be connected?

Yes-the exposed thermal pad (pin 1 index area) must be soldered to a PCB copper pour tied to GND. It is electrically connected to internal GND and thermally essential: omitting it reduces maximum power dissipation from 1825 mW to <300 mW, risking thermal shutdown or premature failure under 100 mA loads.

How does Q7S support cascading better than standard serial-out pins?

Q7S is clocked on the falling edge of SHCP-providing guaranteed setup time for the next device's DS input before its rising-edge SHCP arrives. This built-in timing margin (≥40 ns) ensures reliable data capture across multiple daisy-chained NPIC6C596BQ,115 devices, even at 10 MHz clock rates, without requiring external delay circuits or layout tuning.
