1 Half -Bridge Driver Features Floating high-side driver in bootstrap operation to 600V Drives two N-channel MOSFETs or IGBTs in a half bridge configuration Outputs tolerant to negative transients Programmable dead time to protect MOSFETs Wide logic and low side gate driver supply voltage: 10V to 20V Wide logic supply voltage offset voltage: -5V to 5V Logic input ( and ) 3.3V capability Schmitt triggered logic inputs with internal pull down Undervoltage lockout for high and low side drivers Extended temperature range:-40 C to +125 C Description The is a high voltage, high speed gate driver capable of driving N-channel MOSFETs and IGBTs in a half bridge configuration. Telefunken s high voltage process enables the s high side to switch to 600V in a bootstrap operation. The logic inputs are compatible with standard TTL and CMOS levels (down to 3.3V) to interface easily with controlling devices. The driver outputs feature high pulse current buffers designed for minimum driver cross conduction. Programmable dead time, by an external resistor, provides more system level flexibility. The is offered in PDIP-14 and SOIC-14(N) packages. It operates over an extended -40 C to +125 C temperature range.
