Intersil Introduces Radiation Hardened Full Bridge N-Channel FET Driver
PALM BAY, FL, January 18, 2000 — Intersil Corporation announced today its radiation hardened (Rad Hard), full bridge, N-Channel FET driver integrated circuit (IC). Intersil’s HS-4080ARH is suited for use in distributed DC power supplies, DC to DC converters and motor control applications. The device is immune to single event latch-up, is tested and guaranteed to 300k RADs total dose and is designed to greatly reduce sensitivity to low dose rate effects.
PALM BAY, FL, January 18, 2000 Intersil Corporation announced today its radiation hardened (Rad Hard), full bridge, N-Channel FET driver integrated circuit (IC). Intersils HS-4080ARH is suited for use in distributed DC power supplies, DC to DC converters and motor control applications. The device is immune to single event latch-up, is tested and guaranteed to 300k RADs total dose and is designed to greatly reduce sensitivity to low dose rate effects.
The HS-4080ARH includes a TLL-level input comparator that can be used to facilitate hysteresis and pulse width modulation (PWM) modes of operation. A single HS-4080ARH device can drive medium voltage motors. Micro-stepping capability is enabled through a short minimum on-time that is required for driving high performance stepper motors.
Short propagation delays maximize control loop crossover frequencies and dead time. Precise control of the driven load can be achieved through the minimization of distortion by adjusting the crossover frequencies to near zero. The high enable (HEN) pin forces current to freewheel in the bottom two external MOSFETs, maintaining the upper power MOSFETs off.
About Star*Power
The Star*Power product family includes Intersils next generation Rad Hard MOSFETs, Rad Hard power management ICs and a developing Rad Hard DC to DC converter portfolio. Products currently include MOSFET drivers, bridge drivers, comparators, regulators and references, and the family will soon include Intersils GEN III Rad Hard MOSFET devices. To round out the Star*Power family, Intersil will offer a family of high efficiency DC to DC converters which are compliant to MIL-STD 461D, meet 100k RAD total dose, and mitigate single event effects. Intersils Star*Power products allow satellite manufacturers to minimize part count, utilize the advantages of distributed power design techniques and ensure the survivability of satellites in harsh radiation environments. Star*Power components exhibit rugged total dose radiation performance and single event effects immunity and are best employed when failure is not an option in spacecraft power systems. Star*Power information can be obtained by logging onto Intersils Web site at www.intersil.com, or requesting brochure BR-126.1 from your nearest Intersil sales location.
Intersils radiation hardened IC and discrete devices are commercially available standard product items and are outstanding Commercial Off the Shelf (COTs) solutions for Satellite systems applications.
