Low RDS(on) power MOSFETs.
Programmable power MOS slew rate.
Up to 1/16 microstepping.
Current control with adaptive decay.
Non-dissipative current sensing.
SPI interface.
Low quiescent and standby currents.
Programmable non-dissipative overcurrent protection on all power MOS.
Two-level overtemperature protection.
