LF2136B 3-Phase Half Bridge Gate Driver Features Description T hree floating high-side drivers in bootstrap LF2136B is a three-phase gate driver IC designed for high operation to 600V voltage, high speed applications, driving N-channel 200mA source / 350mA sink output current MOSFETs and IGBTs in a half-bridge congfi uration. The capability high voltage process enables the LF2136B high sides to Outputs tolerant to negative transients, dV/dt switch up to 600V in a bootstrap operation. immune LF2136B logic inputs are compatible with standard Wide VCC operating range: 10V to 20V TTL and CMOS levels (down to 3.3V) to interface Logic input 3.3V capability easily with controlling devices and are enabled low to Internal deadtime of 290ns to protect MOSFETs better function in high noise environments. The driver Matched propagation delay for all channels outputs feature high pulse current buffers designed Outputs out of phase with inputs for minimum driver cross conduction. Schmitt triggered logic inputs LF2136B oerff s nu merous protection functions. A Cross conduction prevention logic shoot-through protection logic prevents both outputs Under Voltage Lockout (UVLO) for all channels being high with both inputs low (fault state), an Overcurrent protection shuts down drivers under-voltage lockout (UVLO) for V shuts down all CC drivers through an internal fault control, while a UVLO for V shuts down the respective high side output. BS Additionally an overcurrent protection will terminate all six outputs. Both the V UVLO and the overcurrent CC protection activate an automatic fault clear with a timing that is adjustable with an external capacitor. Applications LF2136B is offered in an SOIC-28 package and 3-Phase Motor Inverter Driver operates over an extended temperature range of White Goods - Air Conditioner, Washing Machine, -40 C to +125 C .
