TPIC6A596DW

TPIC6A596DW Description

The TPIC6A596DW from Texas Instruments is an 8-bit shift register designed for high-voltage, high-current applications. Housed in a 24-SOIC package, this surface-mount device integrates a serial-to-parallel conversion function with open-drain outputs, making it ideal for driving inductive or resistive loads. Operating within a 4.5V to 5.5V supply range, it ensures reliable performance in industrial and automotive environments. The device is RoHS3 compliant and carries an EAR99 ECCN designation, indicating its suitability for global export.

TPIC6A596DW Features

• 8-bit serial-in, parallel-out shift register with open-drain outputs (50V, 150mA per channel).
• High-voltage tolerant (up to 50V), enabling direct control of power loads like relays, LEDs, or solenoids.
• Serial-to-parallel conversion with cascadable functionality for expanded output channels.
• Wide operating voltage (4.5V–5.5V), ensuring compatibility with standard logic levels.
• Robust construction: REACH unaffected, MSL 1 (unlimited) moisture sensitivity, and obsolete status (still available but not recommended for new designs).
• Low-power consumption compared to discrete driver solutions, reducing system complexity.

TPIC6A596DW Applications

• Automotive systems: Power distribution modules, lighting controls, and actuator drivers.
• Industrial automation: Relay/valve control, motor driver interfaces, and PLC output stages.
• LED displays: Multiplexed high-current LED arrays or signage.
• Power management: Load switching in battery-operated or high-voltage systems.
• Legacy system maintenance: Repair or replacement in existing designs requiring high-current shift registers.

Conclusion of TPIC6A596DW

The TPIC6A596DW excels in high-current, high-voltage applications where serial-to-parallel conversion and open-drain driving are critical. Its integration of logic and power stages reduces board space and component count, while its 50V output tolerance ensures durability in harsh environments. Though obsolete, it remains a viable choice for legacy systems or niche designs requiring its unique combination of features. Engineers should evaluate newer alternatives for forward-looking projects but can rely on this IC for proven performance in demanding scenarios.
