[AP1011] AP1011 9V Dual H-Bridge Motor Driver IC General Description The AP1011 includes 2 channel H-bride drivers in one package. It also includes Under voltage Detection and Thermal Shut Down circuits. It is suitable for driving stepper motor and voice coil motors. Featureｓ □ 2 channel H-bridge drivers in one package □ Power Supply Voltage Range Control (VDD) ： 2.7V～5.5V Motor （VB） ： 2.0V～7.0V（VDDmax=5.5V） 2.0V～9.0V（VDDmax=3.6V） □ Output Current ： 0.7A（DC）, 1.4A(Peak) □ Low ON Resistance ： RDSON (TOP+BOT)=0.54Ω（TYP）@25℃ or 0.72Ω（TYP）@85℃ □ Possible High Frequency PWM Pulse Input ： max 200kHz □ Built in Flow-through Current Protection Circuit □ Built in Charge Pump Circuit □ Built in UVLO & TSD Circuits □ Package ： 16pin 3mm×3mm QFN ＜MS1292-E-00-Web＞ AKEMD CONFIDENTIAL 1 2011/11 [AP1011] Block Diagram TSD Thermal Shut Down Under Voltage Detection UVDN VB1 VG CH Charge Pump CL OUT1A OUT1B UVDN VDD VDD Level Shifter GND1 Pre-Driver VB2 TSD IN1A IN1B OUT2A Control Logic OUT2B IN2A IN2B GND2 Fig1．Block diagram □ H-bridge driver block NMOS type FETs are applied both high side and low side FETs of a H-bridge. □ Charge pump block It generates the drive voltage (VG) of gate for a high side FET. □ Control logic block Each H-bridge driver is controlled by two input signal IN1/2A or IN1/2B. □ Level shifter & pre-driver block Control signals for the high side FET is shifted VG voltage and then drive the gate of the high side FET. □ Under Voltage Detection It is monitoring the control voltage （VDD）, if the VDD is less than the specified voltage, the output of the H-bridge goes to high impedance. □ Thermal Shut Down If the temperature of the chip is more than the specified temperature, the output of the H-bridge goes to high impedance. ＜MS1292-E-00-Web＞ AKEMD CONFIDENTIAL 2 2011/11 [AP1011] Absolute Maximum Ratings Ta = 25℃ unless otherwise specified.

(note2) Product quality may suffer if the absolute maximum rating is exceeded even momentarily for any parameter. That is, the absolute maximum ratings are rated values at which the products on the verge of suffering physical damages, and therefore products must be used under conditions that ensure that the absolute maximum ratings are not exceeded. (note3) The ON time must be less than 10ms and the ON time duty cycle must be less than 5%. (note4) Assembly condition: When the 2-layer(pattern rate:150%) board is used. This is calculated RθJ=60℃/W. Recommended Operating Conditions Ta = 25℃ unless otherwise specified.
