MC33PT2001 Programmable solenoid controller Rev. 7 5 November 2019 Product short data sheet 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. 2 Features and benefits Programmable integrated End-of-Injection (EOI) measurement function Outputs configurable into 2-bank operation Five high-side / seven low-side predrivers: PWM frequency: 100 kHz Four programmable slew rates: 12.5 V/s to 300 V/s Flexible current profile management through four programmable microcores running at 6 MHz Automatic freewheeling control Programmable integrated diagnostics: openload undervoltage overvoltage overcurrent overtemperature Independent DRVEN pin for safety ISO 26262 compliant development Embedded encryption for microcode protection 16-bit SPI control with IRQB plus three interrupt flags 36 V tolerant digital IOsNXP Semiconductors MC33PT2001 Programmable solenoid controller 3 Simplified application diagram Figure 1.Simplified application diagram 4 Applications Automotive (12 V), truck and industrial (24 V) powertrain Gasoline Direct Injection (GDI) Diesel Direct Injection (DDI) CNG / LNG engines Variable Valve Actuators (VVA) Active suspension systems Transmission solenoid drivers (CVT, DCT, AT) MC33PT2001 SDS All information provided in this document is subject to legal disclaimers.
