1 General description
The PT2001 is a SMARTMOS programmable gate driver IC for solenoid control in
automotive application. The typical application is engine control. A wide range of system
configurations is also supported.
The general architecture comprises the combination of a set of programmable
microcores, integrated high-side (x5), and low-side (x7) predrivers for discrete logic level
MOSFETs, end of injection detection and means for diagnostics and protection against
external faults. Both battery voltage and booster voltage level high-side configurations
are supported. The chip communicates with the main controller through an SPI bus and a
flexible set of direct interface signals.
The main characteristics of this component are:
The programmable architecture: the four dedicated microprocessor cores optimized to
control power MOSFETs with small latency time. Thus a high level of flexibility during
design and at runtime can be achieved.
The high level of integration: all interfaces are designed to use as few external
components as possible.
