features applications typical applications circuit ? 8 or 12 high current outputs ? r on = 1.5? (typ.) i max = 350ma ? outputs combinable for higher loads ? digital voltage range vdd 3.3v or 5.0v ? low standby current < 1a @50c ? low output leakage < 5a @13v, rt ? spi interface with diagnostics ? open load detection ? short circuit limitation, - detection ? output clamping for inductive loads typ. >40v ? thermal overload protection ? -40c to +125c operation temperature (qfn) ? stepper motor driver with stall detection ? dc motor driver with pwm ? relay driver with vbat- automatically pwm ? led driver with 3 logarithmic pwm sources ? switch monitoring with pulsed current check and control lamp ? switch monitoring with control lamp general description the ic drives 2 or 3 unipolar stepper motors and pro - vides an optional stall detection for end position detec - tion. for led dimming a quasi logarithmic duty cycle is following the physiology of the human eye. with 3 pwm sources color leds can be driven in 3-color led mode (245hz pwm). the relay pwm mode automati - cally adjusts the pwm to an effective supply voltage of typ. 11v. all outputs are short circuit and over-temper - ature protected with error read back capability. switch monitoring with control lamp combination with only 1 wire and output is possible. ordering information product id channels stall detection package e520.01 12 x qfn32l5, soic28 e520.02 12 qfn32l5, soic28 e520.03 8 x qfn32l5 qfn20l5, soic20 e520.08 8 qfn32l5 qfn20l5, soic20 external c interface overtemp. detection e520.01, e520.02, e520.03, e520.08 * e520.01, e520.03 only ** e520.01, e520.02 only ** vdd vbat_sense vdd d vbat c vbat c vdd vdd resetb ceb sclk si so m m m out0-3 sleep mode control c vbat_sense vbat 4 current sense + limitation stall detection* driver control clamping 4 out4-7 out 8-11 elmos semiconductor ag info sheet qm-no.: 25is0054e.01 12 / 8 channel l ow side d river with stall d etec tion e520.01/02/03/08 this document contains information on a pre-production product. elmos semiconductor ag reserves the right to change specifcations and information herein without notice. preliminary in f ormation - jun 30, 2012
