CISSOID - High temperature driver for power MOSFETs in DC-DC converters and electric motor control

With a typical on-resistance of 1 Ohm, both high-side and low-side 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 35V 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.

HYPERION further enhances the high temperature product portfolio of CISSOID and it confirms the company’s continued focus on high temperature DC-DC converters, electric motor drivers and inverters, especially for the transportation industry (electric and hybrid cars, train, aeronautics) and oil & gas applications.
