Application Notes z The 11-MD114 is 1.5 CH constant current driver for use in M-shutter and Iris. The range of one supply voltage of 11-MD114, VDD is from 1.75V to 5.5V, and the other supply voltage of 11-MD114, VB, its maximum rating voltage can reach to 5.5V. The 11-MD114 input range is defined that logic “H” is from 0.8*VDD to VDD+0.4V and logic “L” is from –0.4V to 0.2*VDD. The input pins, IN1, IN2, IN3, are motor rotation selection pins.

Page 8 MD114 z Normally VB should provide enough current for output loading, thus large value of capacitor such as is suggested for the terminal VB. Besides, 0.01uF~0.1uF of capacitors are also suggested between each output channel and output channel to ground. z The settling time from standby mode to output ready is about 10us. The main difference between STANDBY1 and STANDBY2 depends on voltage reference in the internal circuit is ready or not. In general, the rising time of constant current from the mode, STANDBY2, to the mode, O1 & O2 (or O2 & O3) should be faster than that of the mode, STANDBY1. However, the supply current I STB 2 is larger than that of I STB1 , there is the tradeoff between the rising time and the amount of supply current. z Constant current operation of 11-MD114 provides the current, which can be 0.2 evaluated by the formula I = ( A ) . It is obviously that constant current RFG ( Ω ) depends on the loading resistance of the terminal, RFG. Therefore, how to reduce the effect of line resistance from the terminal, RFG, to GND, will decide the accuracy of constant current. z The power dissipated by the IC varies widely with the supply voltage, the output current, and loading. It is important to ensure the application does not exceed the allowable power dissipation of the IC package. The recommended motor driver power dissipation versus temperature is depicted as follows: Pdmax VS Ta Power Dissipation(mW) 1000 JESD51-7 900 800 870mW 700 600 JESD51-3 500 400 486mW 300 200 100 0 25 50 75 100 125 Ambient Temperature ( ℃ ) Motor Driver for Mobile Phone Version：A.007 未經授權而逕予重製、複製、使用或公開本文件，行為人得被追究侵權之相關民刑事責任 Unauthorized reproduction, duplication, use or disclosure of this document will be deemed as infringement.
