The TK75050 is a non-inverting buffer to drive high power insulated gate transistors (e.g., MOSFETs and IGBTs). The output can source or sink 2 A into a 10,000 pF equivalent load. The IC features built-in cycle-by-cycle current limiting. Its Undervoltage Lockout (UVLO) circuit is combined with a First Pulse Wake-up Feature*. The chip has thermal overload protection. Using the IC in the Gate Charge Recovery* application, the switching spike developed across the current sense resistor practically becomes negligible. Due to its low standby current and first-pulse wake-up feature, the device can be used in selfbiased power supplies. The IC's high-speed cycle-bycycle current limiting capability eliminates the short circuit runaway problem which characterizes most currentcontrolled converters. The IC is well suited to provide supplementary overload protection in voltage-controlled converters, too. The TK75050 is available in the widely used 8-pin DIP package. |
