Infineon TDA21472 transistor

The TDA21472 internal MOSFET current sense algorithm with temperature compensation achieves superior current sense accuracy versus best-in-class controller-based inductor DCR sense methods. Protection includes cycle-by-cycle over current protection with programmable threshold, VCC/VDRV UVLO protection, phase fault detection, IC temperature reporting and thermal shutdown. The TDA21472 also features auto-replenishment of the bootstrap capacitor to prevent over-discharging. The TDA21472 features a deep-sleep power saving mode, which greatly reduces the power consumption when the multiphase system enters PS3/PS4 mode.
