DS3668 - Quad Fault Protected Peripheral Driver

General Description

The DS3668 quad peripheral driver is designed for those applications where low operating power, high breakdown voltage, high output current and low output ON voltage are required.

Unlike most peripheral drivers available, a unique fault protected circuit is incorporated on each output.

Key Features

  • n Output fault protection n High impedance TTL compatible inputs n High output current.
  • 600 mA per output n No output latch-up at 35V n Low output ON voltage (550 mV typ @ 600 mA) n High breakdown voltage (70V) n Open collector outputs n Output clamp diodes for inductive fly-back protection n NPN inputs for minimal input currents (1 µA typical) n Low operating power n Standard 5V power supply n Power up/down protection n Fail-safe operation n 2W power package n Pin-for-pin compatible wi.

DS3668 Quad Fault Protected Peripheral Driver January 2001 DS3668 Quad Fault Protected Peripheral Driver General Description The DS3668 quad peripheral driver is designed for those applications where low operating power, high breakdown voltage, high output current and low output ON voltage are required. Unlike most peripheral drivers available, a unique fault protected circuit is incorporated on each output. When the load current exceeds 1.0A (approximately) on any output for more than a built-in delay time, nominally 12 µs, that output will be shut off by its protection circuitry with no effect on other outputs. This condition will prevail until that protection circuitry is reset by toggling the corresponding input or the enable pin low for at least 1.0 µs.
