Nexperia USA Inc. NPIC6C595PW,118

Overview

NPIC6C595PW,118 from Nexperia is an 8-bit serial-in/parallel-out shift register with open-drain extended-drain NMOS outputs, separate shift and storage register clocks (SHCP and STCP), asynchronous master reset (MR), and active-low output enable (OE). It delivers 100 mA continuous current per channel, 33 V drain-source breakdown voltage, and integrated inductive transient protection-used to drive LEDs, relays, and solenoids in industrial status panels.

For engineers reviewing the NPIC6C595PW,118 datasheet, NPIC6C595PW,118 pinout, NPIC6C595PW,118 application, or NPIC6C595PW,118 equivalent, key selection criteria include open-drain output voltage clamping (33 V), R_DS(on) ≤ 10 Ω at 100 mA, -40 °C to +125 °C operation, cascading capability via Q7S, and thermal-enhanced TSSOP16 packaging for high-current power logic interfacing.

Technical Context

The device implements dual-register architecture: an 8-stage shift register accepts serial data on SHCP rising edges and feeds Q7S for daisy-chaining, while a parallel-access storage register latches data on STCP rising edges to drive outputs. MR asynchronously clears both registers; OE independently controls output state without affecting register contents.

Each of the eight Q0–Q7 outputs integrates an extended-drain NMOS transistor rated for 33 V V_(BR)DSS, 100 mA continuous current, and 30 mJ single-pulse avalanche energy-enabling direct switching of moderate-power inductive and resistive loads without external flyback components.

FAQ

What is the maximum safe continuous current per output when operating at 125 °C ambient?

At Tamb = 125 °C, the maximum continuous current per output is 100 mA, as specified in Table 3 (Limiting Values) and confirmed in Table 4 (Recommended Operating Conditions). Derating is not required for current-but total power dissipation must remain within 145 mW for the TSSOP16 package, limiting simultaneous full-load channel count based on thermal design.

Can NPIC6C595PW,118 drive a 24 V relay coil directly without external protection components?

Yes-the integrated 30 mJ avalanche energy capability and 33 V V_(BR)DSS rating allow direct connection to 24 V DC relay coils. The internal extended-drain NMOS handles inductive kickback without external flyback diodes, provided coil energy remains within the single-pulse avalanche limit (verified per Fig. 9 test conditions).

How does the dual-clock architecture prevent output glitches during data loading?

Separate SHCP (shift) and STCP (storage) clocks decouple data shifting from output updating. Data shifts serially on SHCP edges but remains isolated in the shift register until STCP triggers transfer to the storage register-and only then are outputs updated. This eliminates partial updates and ensures atomic output state changes.

Is the exposed thermal pad on the TSSOP16 package electrically connected or required for thermal performance?

No-the exposed pad on SOT403-1 (TSSOP16) is not electrically connected and has no electrical function. While it may improve thermal conduction when soldered to a copper pour, the datasheet explicitly states there is no electrical or mechanical requirement to solder it; if used, the land must remain floating or tied to GND per layout guidance in Figure 8.
