1 / 12 page January 1996 INT200 Low-side Driver IC Low-side Drive and High-side Control with Simultaneous Conduction Lockout Product Highlights 5 V CMOS Compatible Control Inputs • Combines logic inputs for low and high-side drives • Schmidt-triggered inputs for noise immunity Built-in High-voltage Level Shifters • Integrated level shifters simplify high-side interface • Can withstand up to 800 V for direct interface to the INT201 high-side driver • Pulsed high-voltage level shifters reduce power consumption Gate Drive Output for an External MOSFET • Provides 300 mA sink/150 mA source current • Can drive MOSFET gate at up to 15 V • External MOSFET allows flexibility in design for various motor sizes Built-in Protection Features • Simultaneous conduction lockout protection • UV lockout Description The INT200 Low-side driver IC provides gate drive for an external low-side MOSFET switch and high-side level shifting. When used in conjunction with the INT201 high-side driver, the INT200 provides a simple, cost-effective interface between low-voltage control logic and high-voltage loads. The INT200 is designed to be used with rectified 110 V or 220 V supplies. Both high-side and low-side switches can be controlled independently from ground-referenced 5 V logic inputs on the low side driver. Built-in protection logic prevents both switches from turning on at the same time and shorting the high voltage supply. Pulsed level shifting saves power and provides enhanced noise immunity. The circuit is powered from a nominal 15 V supply to provide adequate gate drive for external N-channel MOSFETs. Applications include motor drives, electronic ballasts, and uninterruptible power supplies. The INT200 can also be used to implement full- bridge and multi-phase configurations. The INT200 is available in 8-pin plastic DIP and SOIC packages. ® ORDERING INFORMATION PART PACKAGE ISOLATION NUMBER OUTLINE VOLTAGE INT200PFI1 P08A 600 V INT200TFI1 T08A 600 V INT200PFI2 P08A 800 V INT200TFI2 T08A 800 V HSD2 HS IN PI–284C–072291 COM 8 5 7 6 N/C LS IN LS OUT 1 4 2 3 VDD HSD1 Figure 2.
