Applications

Typical Applications Circuit ÿ 8 or 12 high current outputs ÿ RON = 1.5Ω (typ.) IMAX = 350mA ÿ Outputs combinable for higher loads ÿ Digital voltage range VDD 3.3V or 5.0V ÿ Low standby current < 1µA @50°C ÿ Low output leakage < 5µA @13V, RT ÿ SPI interface with diagnostics ÿ Open load detection ÿ Short circuit limitation, - detection ÿ Output clamping for inductive loads typ. >40V ÿ Thermal overload protection ÿ -40°C to +125°C operation temperature (QFN) ÿ Stepper Motor Driver with Stall Detection ÿ DC Motor Driver with PWM ÿ Relay Driver with VBAT- automatically PWM ÿ LED Driver with 3 logarithmic PWM sources ÿ Switch Monitoring with pulsed current check and control lamp ÿ 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.
