A6595
8-Bit Serial-Input DMOS Power Driver

Features

• 50  V minimum output clamp voltage
• 250 mA output current (all outputs simultaneously)
• 1.3 Ω typical r_DS(on)
• Low power consumption
• Replacements for TPIC6595N and TPIC6595DW

Description

The A6595 combines an 8-bit CMOS shift register and accompanying data latches, control circuitry, and DMOS power driver outputs. Power driver applications include relays, solenoids, and other medium-current or high-voltage peripheral power loads.

The serial-data input, CMOS shift register and latches allow direct interfacing with microprocessor-based systems. Serialdata input rates are over 5 MHz. Use with TTL may require appropriate pull-up resistors to ensure an input logic high.

A CMOS serial-data output enables cascade connections in applications requiring additional drive lines.

The A6595 DMOS open-drain outputs are capable of sinking up to 750 mA. All of the output drivers are disabled (the DMOS sink drivers turned off) by the OUTPUT ENABLE input high.

The A6595 is furnished in a 20-pin dual in-line plastic package that is lead (Pb) free, with 100% matte tin leadframe plating. Copper leadframe base material, reduced supply current requirements, and low on-state resistance allow the device to sink 150 mA from all outputs continuously, to ambient temperatures to 125°C.
