The TPIC6A595DW from Texas Instruments is a high-voltage, high-current power logic 8-bit shift register designed for use in systems that require relatively high load power. It integrates a built-in Darlington transistor array, which allows it to drive heavy loads directly with good thermal performance. This makes it an ideal choice for applications such as LED displays, printer and copier controls, relay drivers, and lamp drivers.

Key Features

• Integrated Circuit: The device combines an 8-bit serial-in, parallel-out shift register and a storage register with the capability to perform direct clear.
• Output Ratings: With a 45-V maximum V_CC and a 350-mA continuous current rating per channel, the TPIC6A595DW can handle a significant amount of power.
• High-Voltage Outputs: The open-drain DMOS transistor outputs can sink a significant current at high voltage, up to 50V, allowing for direct operation of a wide range of inductive and resistive loads.
• Robust Design: The device features built-in clamp diodes for inductive load transient suppression, enhancing its durability and reliability in harsh environments.
• Flexible Operation: The shift register has both shift clock (SRCK) and storage register clock (RCK) inputs, providing flexibility in timing for data input and output.
• Easy Cascading: Multiple TPIC6A595DW devices can be cascaded without additional circuitry, allowing for the expansion of output capability without compromising performance.

Applications

The TPIC6A595DW is versatile and can be used in a variety of applications. Its ability to drive high currents and voltages with thermal protection makes it suitable for controlling solenoids, relays, DC motors, and other high-current or high-voltage loads. It is also commonly used in LED display boards, due to its capability to sink current for multiple LEDs simultaneously.

Package and Quality

The TPIC6A595DW is offered in a 20-pin SOIC package, ensuring a compact footprint while providing adequate thermal performance for most applications. As with all Texas Instruments products, this device is manufactured to high standards, ensuring high reliability and performance consistency.
