The STMicroelectronics L6220 is a Quad Darlington Switch integrated circuit. This component is designed for applications requiring robust switching capabilities, particularly when driving inductive loads. The internal logic facilitates easier full-step driving using only two input signals.
Key electrical characteristics include peak collector current ratings, which vary depending on the number of contemporary working outputs. For reliable operation with inductive loads, a zener diode in series with the integral free-wheeling diodes is suggested, with a recommended limit of Vp + Vz < 35 V to manage energy discharge and speed current decay. The device also specifies soldering temperature and time limits to ensure proper assembly.
Mounting instructions suggest that the thermal resistance can be reduced by soldering the GND pins to a suitable copper area of the printed circuit board or an external heatsink. The external heatsink or copper area must be connected to electrical ground. The L6220 is categorized under Power Management PMIC, specifically within the LED Drivers subcategory.
For reliability when driving inductive loads, it is suggested that the zener voltage be chosen such that Vp + Vz < 35 V.
During soldering, the pins temperature must not exceed 260°C and the soldering time must not be longer than 12 seconds.
The thermal resistance can be reduced by soldering the GND pins to a suitable copper area of the printed circuit board or to an external heatsink.
