IR Introduces 200V ICs for Low-Voltage Motor Drive Applications Requiring Compact Footprint.

EL SEGUNDO, Calif. -- International Rectifier, IR[R] (NYSE:IRF), a world leader in power management technology, today introduced a series of 200V ICs for low- and mid-voltage motor drive applications including power tools, low-voltage servo drives, electric garden equipment, and electric vehicles such as cranes, golf carts, and scooters.

The IRS200x family of half-bridge, high-side and low-side driver ICs is tailored for low-voltage (24V, 36V, and 48V) and mid-voltage (60V, 80V and 100V) motor drive applications including both three-phase inverter and half-bridge. Under-voltage lockout (UVLO) protection is a standard feature provided across the family while the IRS2003 and IRS2004 also include deadtime protection. In addition, the IRS2004 features a shutdown input pin. These new 200V ICs feature low quiescent current that enables a low-cost bootstrap power supply for the high-side circuitry, eliminating the need for large and expensive auxiliary power supplies that discrete optocoupler- or transformer-based designs typically require, making them well suited for low-voltage applications that require a small footprint.

"To meet the demand of lower voltage applications, IR has added these rugged new 200V devices to our 600V and 1200V HVIC portfolio," said David New, IR's motor control product manager. "When combined with our independent high- and low-side driver ICs, and DirectFET[R] MOSFETs, this cost-effective system solution delivers high power density and low thermal dissipation in a compact footprint to meet the challenges of three-phase, low-voltage motor drive design," he added.

The IRS200x devices are offered in eight-pin SOIC and DIP packages and feature gate voltage (Vout) up to 20V, typical turn-on current (Io+) of 290 mA, typical turn-off (Io-) current of 600 mA, and accept input logic levels of 3.3V, 5V and 15V. The new 200V devices utilize IR's advanced high-voltage IC process which incorporates next-generation high-voltage level-shifting and termination technology to deliver superior electrical over-stress protection and higher field reliability.
