Introducing the TPIC6B596DW Power Logic 8-Bit Shift Register

The TPIC6B596DW from Texas Instruments is a robust, high-voltage, high-current power logic 8-bit shift register designed for use in systems that require relatively high load power, such as LED displays, industrial controls, and power drivers. This integrated circuit is part of Texas Instruments' TPIC family, which is known for its ability to handle high-voltage outputs with enhanced durability.

The device incorporates an 8-bit serial-in, parallel-out shift register that feeds an 8-bit D-type storage register. In the output stage, eight regulated open-drain DMOS transistor outputs provide the high-current and high-voltage capabilities, with each channel capable of sinking a significant current, making it suitable for directly driving LEDs or other high-current loads without the need for additional power transistors.

Key features of the TPIC6B596DW include:

• High-Voltage Output: The device can handle up to 50V on the output side, which allows it to drive a series of LEDs or other high-voltage components.
• High-Current Sink: Each output can sink up to 150 mA, providing the ability to drive multiple LEDs in series or other power-hungry loads.
• Low Power Consumption: With a typical low power consumption, it is well-suited for portable and battery-powered applications.
• Enhanced Thermal Performance: The TPIC6B596DW comes in a wide-body SOIC package, which aids in better thermal dissipation.
• Shift Register and Latch Functionality: The built-in shift register and latch allow for easy serial-to-parallel data conversion and output holding capability, respectively.

The device also features a built-in output clamp diodes for inductive transient suppression, which makes it ideal for inductive loads such as relays and solenoids. The TPIC6B596DW is characterized for operation from -40°C to 85°C, ensuring reliable performance across a wide range of environmental conditions.

With its combination of high-voltage and current capabilities, along with the robustness expected from Texas Instruments, the TPIC6B596DW is a versatile solution for designers looking to improve their power driving applications.
