High-Performance Power ICs and Hall-Effect Sensors

A6259
8-Bit Addressable DMOS Power Driver

Pin-Out or Package

These parts have been phased out of production as of April 28, 2007.

Features

  • 50 V Minimum Output Clamp Voltage
  • 250 mA Output Current (all outputs simultaneously)
  • 1.3 ohms Typical rDS(on)
  • Low Power Consumption
  • Replacements for TPIC6259N and TPIC6259DW

Description

The A6259KA and A6259KLW combine a 3-to-8 line CMOS decoder and accompanying data latches, control circuitry, and DMOS outputs in a multi-functional power driver capable of storing single-line data in the addressable latches or use as a decoder or demuliplexer. Driver applications include relays, solenoids, and other medium-current or high-voltage peripheral power loads.

The CMOS inputs and latches allow direct interfacing with microprocessor- based systems. Used with TTL may require appropriate pull-up resistors to ensure an input logic high. Four modes of operation are selectable with the CLEAR and ENABLE inputs.

The addressed DMOS output inverts the DATA input with all unaddressed outputs remaining in their previous states. All of the output drivers are disabled (the DMOS sink drivers turned off) with the CLEAR input low and the ENABLE input high. The A6259KA/KLW DMOS open-drain outputs are capable of sinking up to 750 mA. Similar devices with reduced rDS(on) will be available as the A6A259.
