1 Features Floating high-side driver in bootstrap operation to 600V Drives two N-channel MOSFETs or IGBTs in a half bridge configuration 290mA source/600ma sink output current capability Outputs tolerant to negative transients Internal dead time of 520ns to protect MOSFETs Wide low side gate driver supply voltage: 10V to 20V Logic input ( and ) 3.3V capability Schmitt triggered logic inputs Undervoltage lockout for (logic and low side supply) 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. has a fixed internal deadtime of 520ns (typical). The is offered in PDIP-8 and SOIC-8(N) packages and operate over an extended -40 C to +125 C temperature range.
