For LED dimming a quasi logarithmic duty cycle Digital voltage range VDD 3.3V or 5.0V is following the physiology of the human eye. With 3 Low standby current < 1A 50C PWM sources color LEDs can be driven in 3-color LED Low output leakage < 5A 13V, RT mode (245Hz PWM). The Relay PWM mode automati- SPI interface with diagnostics cally adjusts the PWM to an effective supply voltage of Open load detection typ. 11V. All outputs are short circuit and over-temper- Short circuit limitation, - detection ature protected with error read back capability. Switch Output clamping for inductive loads typ. >40V monitoring with control lamp combination with only 1 Thermal overload protection wire and output is possible. -40C to +125C operation temperature (QFN) Ordering Information Applications Stall Ordering-No.: Channels Package Detection Stepper Motor Driver with Stall Detection E52001A61C 12 X QFN32L5 DC Motor Driver with PWM E52001A05E 12 X SOIC28 Relay Driver with VBAT- automatically PWM E52002A61C 12 QFN32L5 LED Driver with 3 logarithmic PWM sources E52002A05E 12 SOIC28 Switch Monitoring with pulsed current check and E52003A61C 8 X QFN32L5 control lamp E52003A62C 8 X QFN20L5 Switch Monitoring with control lamp E52003A55E 8 X SOIC20 E52008A61C 8 QFN32L5 E52008A62C 8 QFN20L5 E52008A55E 8 SOIC20 Typical Application Circuit D VBAT VBAT C VBAT CVBAT Sense VDD VDD CVDD VDD VBAT Sense Overtemp.
