Allegro added a high-brightness, adjustable constant current LED driver to its portfolio of display driver ICs. Targeted at the automotive lighting market, this LED driver is also a fit for industrial and consumer LED applications. This device is designed to operate over the typical automotive battery and temperature ranges. The input voltage range is specified down to 6V and will operate up to a maximum of 40V. The linear constant current output can be adjusted to provide up to 350 mA in a typical application. An ENABLE input is used to enable the LED drive and can also be driven with a pulse-width-modulated (PWM) input for dimming of the LED brightness. To help minimize EMI, the slew rate of the output current is controlled during switching. In addition, the ENABLE pin will cause the IC to enter into a low quiescent sleep mode if held low. The IC is fully protected against shorts to ground or shorts to battery. It also includes a thermal shut-down circuit (TSD) which disables the IC if the junction temperature reaches ~ 165°C. The A6260 has integrated reverse battery protection eliminating the need for an external reverse battery diode, and it also includes a temperature monitor circuit.
