Low-voltage motor drives offer compact
footprint
International Rectifier has introduced a series of 200V ICs for low- and mid-voltage motor drive applications which require a compact footprint.
International Rectifier has 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

International Rectifier has introduced a series of single-channel high-voltage integrated circuits for a wide range of applications including motor control, lighting, switch mode power supplies.
Three-phase 600V IC ups drives reliability
A three-phase 600V IC with DC bus sensing and negative voltage spike immunity boosts robustness and reliability in electric motor drive systems.
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.
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 utilise 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.
