Nexperia USA Inc. NPIC6C595BQ-Q100,1

Overview

NPIC6C595BQ-Q100 from Nexperia is an AEC-Q100 Grade 1 qualified 8-bit serial-in/parallel-out shift register with open-drain extended-drain NMOS outputs, separate shift/storage clocks (SHCP/STCP), asynchronous master reset (MR), and active-low output enable (OE). It delivers 100 mA continuous current per channel at 33 V drain-source rating and integrates avalanche energy protection (30 mJ) for driving LEDs, relays, and solenoids in automotive power interface applications.

For engineers reviewing the NPIC6C595BQ-Q100 datasheet, NPIC6C595BQ-Q100 pinout, NPIC6C595BQ-Q100 application, or NPIC6C595BQ-Q100 equivalent, key selection criteria include its DHVQFN16 package with side-wettable flanks for AOI, -40 °C to +125 °C operation, 250 mA pulsed output capability, R_DS(on) ≤ 10 Ω at 100 mA, and integrated voltage clamping for inductive load transients.

Technical Context

The device implements dual-register architecture: an 8-stage shift register clocked by SHCP and an independent 8-bit storage register clocked by STCP, enabling synchronous latching of serially shifted data. Both registers are cleared simultaneously by a single active-low MR input, decoupling reset control from clock timing.

Each of the eight Q0–Q7 outputs uses an extended-drain NMOS transistor with internal source-to-GND connection, rated for 33 V V_DS, 100 mA continuous, and 250 mA pulsed current. Output clamping and 30 mJ non-repetitive avalanche energy handling allow direct drive of inductive loads without external flyback diodes in many automotive implementations.

FAQ

Can NPIC6C595BQ-Q100 drive 24 V incandescent lamps directly?

Yes-it supports up to 33 V V_DS and 100 mA continuous per channel, sufficient for low-power 24 V indicator lamps. However, inrush current must be limited externally if lamp cold resistance causes >250 mA peak surge, as the device's pulsed rating is 250 mA with ≤2% duty cycle and ≤100 μs pulse width.

What is the function of the thermal pad on the DHVQFN package?

The exposed thermal pad (Pin 1 index area) must be soldered to a PCB ground plane to dissipate heat from the eight power outputs. Nexperia specifies it as electrically connected to GND internally; floating or unconnected pads cause thermal derating and potential reliability failure above 85 °C ambient.

How does the MR pin interact with OE and clock signals?

MR is asynchronous and overrides all other inputs: a LOW on MR immediately clears both shift and storage registers to zero, regardless of SHCP/STCP state or OE level. Outputs remain in high-impedance OFF-state if OE is HIGH, or go LOW if OE is LOW-ensuring predictable startup and fault-clearing behavior.

Is cascading multiple NPIC6C595BQ-Q100 devices supported in hardware?

Yes-Q7S (Pin 9) provides buffered serial output synchronized to SHCP, allowing direct connection to DS (Pin 2) of the next device. The datasheet confirms this topology in Fig. 1 and specifies timing margins (e.g., t_pd = 5 ns SHCP→Q7S) to ensure reliable daisy-chaining at up to 10 MHz clock rates.
