Single chip integrates two-channel isolator, 4A driver

Austin, Tex.—Silicon Laboratories Inc. announced the Si823x ISOdriver family of isolated gate drivers targeted at power supplies, motor control and lighting systems.

The ISOdriver family integrates a two-channel isolator and dual driver into a single chip while improving power efficiency, enabling customers to increase power supply density and performance.

Based on Silicon Laboratories' proprietary RF isolator technology and advanced CMOS gate driver design, the ISOdriver family is designed to offer high reliability, increased noise immunity, as well as a 50 percent PCB area reduction compared to competing products, according to the company.

By integrating the isolator and driver into a single chip, the ISOdriver external BOM is reduced to three capacitors and a diode, allowing an isolated high-side/low-side or dual low-side driver solution that occupies 200 mm².

The Si823x devices are available in three input configurations and offer 0.5 and 4 Amp peak output currents. Two control interfaces are also available: two wire and PWM.

Pricing: the Si823x family is priced from $1.25 to $1.70 in quantities of 1K based on configuration and peak output current.
Availability: Now.
