200 V ICs for motor drive applications

8 August 2007 Power Electronics / Power Management

International Rectifier has introduced a series of 200 V 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 (24 V, 36 V, and 48 V) and mid-voltage (60 V, 80 V and 100 V) 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 dead-time protection. In addition, the IRS2004 features a shutdown input pin. These new 200 V 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 20 V, typical turn-on current (Io+) of 290 mA, typical turn-off (Io-) current of 600 mA, and accept input logic levels of 3,3 V, 5 V and 15 V. The new 200 V 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.
