Driver IC lets logic signals control 400V circuits. (Power Integrations PWR-DRV1 integrated circuit) (product announcement)

From: EDN | Date: July 20, 1989| Author: Quinnell, Richard A. | Copyright information

The PWR-DRV1 integrated circuit from Power Integrations Inc features an 8-pin DIP and enables a logic circuit to control such high-voltage components as motors, solenoids and relays. The PWR-DRV1 features a zener diode to create its own 5-volt power from either rectified ac or dc voltage, a 400-volt n-channel MOS power transistor that can manage up to 275 mA of continuous current and up to 2 amps in 300 millisecond pulses with a 2 percent duty cycle, a comparator and a current mirror to sense...

Driver IC lets logic signals control 400V circuits. (Power Integrations PWR-DRV1 integrated circuit) (product announcement)
EDN ; Driver IC lets logic signals control 400V circuits Using the PWR-DRV1 integrated circuit, your logic circuit can control solenoids, relays, motors, or other high-voltage components. This handy IC packs a lot of capability in an 8-pin DIP. For starters, the IC has a zener diode to create its own 5V
Circuit efficiently drives inductive loads.(Technology Information)
EDN ; IN THE DRIVER CIRCUIT in Figure 1, the system controller provides the [V.sub.COMMAND] signal. [V.sub.COMMAND] equals the desired load current multiplied by [R.sub.8]. When the controller applies this voltage to [R.sub.1], the output of [IC.sub.1] goes high, applying voltage to the gates of
Current-limit switch is digitally programmable.(Technology Information)
EDN ; CURRENT-LIMIT SWITCHES are virtually ubiquitous in system controls. They provide a safe means for regulating the current delivered to a load circuit. The switches allow the load current to increase to a programmed limit but no higher. Typically, the current limit is a function of the voltage across

Make Your Own Bidirectional Current-To-Frequency Converter.(Brief Article)(Statistical Data Included)
Electronic Design ; The circuit shown (see figure) converts bidirectional currents to frequency. Its useful current range is from 10 mA to 1 A. Also, the output frequency is proportional to the input current. The Maxim MAX471 (IC1) is a high-side current-sensing device. Its output current is proportional to the load
Optocoupler extends high-side current sensor to 1 kV.(Technology Information)
EDN ; THE TASK OF SENSING dc current at high voltage is often problematic. Most high-side current-sensing ICs available off the shelf are good only to 30 or 40V. Combining an optocoupler with such an IC yields a sensing circuit in which the only limitation of the high-side voltage is the optocoupler's
