1 -A DC电机驱动器伺服驱动器应用 1-A DC Motor Driver for Servo Driver Applications
Description:
The is a protected H-Bridge Driver designed specifically for automotive headlight beam control and industrial servo control applications. The part is built using s bipolar high voltage power technology DOPL.The standard enhanced power PG-DSO-14-22 package meets the application requirements and saves PCB-board space and costs. Moreover the package is RoHS compliant. The servo-loop-parameter pos.- and neg. Hysteresis, pos.- and neg. deadband and angle-amplification are programmable with external resistors. An internal window-comparator controls the input line. In the case of a fault condition, like short circuit to GND, short circuit to supply-voltage, and broken wire, the TLE4206-2G stops the motor
immediately brake condition. urthermore the built in features like over- and undervoltage-lockout, short-circuit-protection and over-temperature-protection will open a wide range of automotive- and industrial applications. The TLE4206-2G is a design-version of the TLE4206. In the TLE4206-2G, the current peak blanking Pin is disconnected. A hysteresis is introduced at the lower RANGE
threshold. This allows reliable de-activation of the device by pulling the RANGE input to GND also under critical application conditions.
