33899

      The 33899 has the following features including Drives Inductive Loads in a Full H-Bridge Configuration;Current Mirror Output Signal (Gain Selectable via External Resistor);Short Circuit Current Limiting;Thermal Shutdown (Outputs Latched Off Until Reset via SPI);Internal Charge Pump Circuit for the Internal High-Side MOSFETs;SPI-Selectable Slew Rate Control and Current Limit Control;Overtemperature Shutdown;Outputs Can Be Disabled to High-Impedance State;PWM-able up to 11 kHz @ 3.0 A;Synchronous Rectification Control of the High-Side MOSFETs;Low RDS(ON) Outputs at High Junction Temperature (< 165 m @ TA = 125°C, VIGNP = 6.0 V);Outputs Survive Shorts to -1.0 V;Pb-Free Packaging Designated by Suffix Code VW.
      The 33899 is designed to drive a DC motor in both forward and reverse shaft rotation under pulse-width modulation (PWM) control of speed and torque. A current mirror output provides an analog feedback signal proportional to the load current. A serial peripheral interface (SPI) is used to select slew rate control, current compensation limits and to read diagnostic status (faults) of the HBridge drive circuits. SPI diagnostic reporting includes open circuit, short circuit to VIGNP, short circuit to ground, die temperature range,and undervoltage on VIGNP.The 33899 is a programmable H-Bridge, power integrated circuit (IC) designed to drive DC motors or bi-directional solenoid controlled actuators, such as throttle control or exhaust gas recirculation actuators. It is particularly well suited for the harsh environment found in automotive power train systems.
      The 33899 is designed to drive a bi-directional DC motor using pulse-width modulation (PWM) for speed and torque control. A current mirror output provides an analog feedback signal proportional to the load current. SPI diagnostic reporting includes open circuit, short-to-battery, short-to-ground, die temperature range and under voltage.Information in this document is provided solely to enable system and software implementers to use Freescale Semiconductor products.
