... LB11600JV Overview The LB11600JV is a direct PWM drive predriver IC appropriate for 3-phase power brushless motors in automotive applications. This IC can implement either high side PWM drive or low side PWM drive motor driver circuits depending on the configuration of the output circuits, which use discrete transistors such as MOSFETs or bipolar transistors. In addition to a full complement of protection functions, including overcurrent, thermal, motor constraint, and undervoltage protection, the LB11600JV also provides an integrated speed control function ...

... Constraint Protection Circuit The LB11600JV includes a constraint protection circuit to protect the motor and the IC itself when the motor is physically prevented from turning. If the Hall input signals do not change for a certain fixed period when the IC is operating in the motor drive state, one side of the output system (the UH, VH, and WH outputs) is turned off. The time is set by the discharge time of the resistor and capacitor connected to the CSD pin ...
