The PT2000 is a SMARTMOS programmable gate driver IC for precisionsolenoid control applications, which makes the component very flexible andrelieves the main microcontroller from the heavy task of the actuator control.The chip integrates six microcores used to control, seven external MOSFEThigh-side pre-drivers, eight external MOSFET low-side pre-drivers (two of themwith higher switching frequency can be used for DC/DC converters), anintegrated end of injection detection, six current measurements, anddiagnostics for both the high-side and low-side.PT2000 includes two internal regulators with overvoltage and undervoltagemonitoring and protection, VCCP fed from the battery line supplying the predriversection and VCC2P5 fed from an external 5.0 V generating supply for thedigital block.Interface with the MCU is achieved via serial peripheral interface (SPI) and 16configurable I/O signals. I/O are supplied by an external 3.3 V or 5.0 V regulatorconnected to VCCIO.These features along with cost effective packaging, make the PT2000 ideal forpower train engine control applications.
