LF2136B

3-Phase Half Bridge Gate Driver

Features

Description

 Three ﬂoating high-side drivers in bootstrap

operation to 600V

 200mA source / 350mA sink output current

capability

 Outputs tolerant to negative transients, dV/dt

immune

 Wide VCC operating range: 10V to 20V

 Logic input 3.3V capability

 Internal deadtime of 290ns to protect MOSFETs

 Matched propagation delay for all channels

 Outputs out of phase with inputs

 Schmitt triggered logic inputs

LF2136Bisathree-phasegatedriverICdesignedforhigh

voltage, high speed applications, driving N-channel

MOSFETs and IGBTs in a half-bridge conﬁguration. The

high voltage process enables the LF2136B high sides to

switch up to 600V in a bootstrap operation.

LF2136B logic inputs are compatible with standard

TTL and CMOS levels (down to 3.3V) to interface

easily with controlling devices and are enabled low to

better function in high noise environments. The driver

outputs feature high pulse current buﬀers designed

for minimum driver cross conduction.

LF2136B oﬀers numerous protection functions. A

shoot-through protection logic prevents both outputs

being high with both inputs low (fault state), an

under-voltage lockout (UVLO) for V_CCshuts down all

drivers through an internal fault control, while a UVLO

for V_BSshuts down the respective high side output.

Additionally an overcurrent protection will terminate

all six outputs. Both the V_CCUVLO and the overcurrent

protection activate an automatic fault clear with a

timing that is adjustable with an external capacitor.

 Cross conduction prevention logic

 Under Voltage Lockout (UVLO) for all channels

 Overcurrent protection shuts down drivers
