Featuring reliable operation from -55°C up to +225°C, the Hyperion high-side and low-side driver is suitable for driving MOSFETs in DC-DC converters and for half-bridge driver designs in electric motor control applications and power inverters. With a typical on-resistance of 1 ?, both high-side and low-side types can drive up to 1-nF loads with a 40-ns propagation delay and 15-ns transition time at 200°C. Internal, adaptive non-overlap circuitry further reduces switching losses by preventing simultaneous conduction when used in MOSFET drive applications. The high-side floating driver is bootstrapped and can accommodate voltages as high as 35 V on the bootstrap node. An under-voltage lockout function holds the high-side switch off until the driver has sufficient voltage for proper operation. A crowbar input turns on the low-side driver independently of the input signal state, and a low-side disable pin allows operation in non-synchronous mode. A shut-down pin turns off both the high-side and the low-side drivers. The Hyperion power-MOSFET driver is available now for sampling and evaluation in a ceramic DIL28 package. Pricing starts at $250.53 each for up to 200 units. CISSOID, Mont-Saint-Guibert, Belgium. +32 10 48 92 10.
