TPIC6A259DWR

Overview

The TPIC6A259DWR is a power logic 8-bit addressable latch featuring open-drain DMOS outputs. It operates with a logic supply voltage (VCC) of 4.5 V to 5.5 V and supports a maximum drain-to-source voltage of 50 V. The device provides eight independent outputs, each capable of delivering a continuous current of 350 mA at 25°C case temperature. It includes internal chopping current-limiting circuits for short-circuit protection and handles single-pulse avalanche energy up to 75 mJ. The component is characterized for operation within an operating case temperature range of -40°C to 125°C.

Feature Summary

• Provides four distinct function modes: addressable latch, memory, 8-line demultiplexer, and clear.
• Features independent chopping current-limiting circuits on each output to prevent damage during short circuits.
• Includes separate power ground (PGND) and logic ground (LGND) terminals to minimize parasitic impedance and crosstalk.
• Integrates a charge pump circuit to support high-voltage switching capabilities.

Applications

• General-purpose storage applications in digital systems
• Working registers and serial-holding registers
• Decoders or demultiplexers

Procurement Notes

Verify the specific ordering suffix against the manufacturer's package option addendum to confirm the carrier type. The 'DW' designation indicates a wide-body surface-mount package. Confirm whether the procurement request requires tube packaging or tape-and-reel quantities, as availability varies by suffix variant. Ensure the selected part matches the required thermal and electrical specifications for the target application environment.

Selection Notes

Select this component when designing systems requiring individually addressable high-current loads with integrated protection. The DW package offers thermally enhanced performance suitable for surface-mount assembly. Consider the separate PGND and LGND requirements for proper grounding strategies. Evaluate the thermal resistance characteristics if multiple outputs will conduct simultaneously to ensure junction temperatures remain within safe operating limits.

Part Context

The TPIC6A259DWR belongs to Texas Instruments' power logic family, specifically designed for driving medium-power loads. It serves as a bridge between low-voltage digital control logic and higher-voltage power circuits. The device replaces discrete transistor solutions by integrating control logic, level shifting, and power drivers into a single monolithic IC, simplifying board layout and reducing component count.
