Unipolar Hall-Effect Switch features built-in diagnostics.

With integrated coil surrounding Hall sensing element,Â- A1160 functions asÂ- typical unipolar switch during normal operation: output turns on in presence of south-pole magnetic field and off when field is removed. Diagnostics modeÂ- lets current pass through integrated coils, generating ~20 G of magnetic field. Proximity of coils to Hall sensing elementÂ- lets element sense field...

Xenon Photoflash Charger ICs come in 2 x 2 mm DFN package.

Offering charge and trigger voltage logic thresholds set at 1 VHI, models A8732 and A8735 support applications implementing low-voltage control logic, such as mobile phones. Current limit for A8732 can be programmed from 0.45-1.5 in 16 steps with single wire interface, while for A8735 it is fixed at 1 A. Utilizing primary-side voltage sensing, devices eliminate need for secondary-side voltage...

LED Driver suits medium LCD display backlighting.

Targeting automotive applications, Model A8501 integrates boost converter and four 100 mA current sinks. LED channels can be tied together for up to 400 mA sink capability. Operating from single power supply of 8-21 V, constant frequency, current-mode converter withstands up to 40 V. Operating frequency can be set up to 2 MHz to avoid interference with AM radio bands. Pb-free IC is housed in...

Current Sensor offers 120 kHz bandwidth.

Featuring 100 Â-µW integrated current conductor, 50-200 A Model ACS758 provides AC or DC current sensing. Thermally enhanced device consists of linear Hall sensor circuit with copper conduction path. Applied current flowing through conduction path generates magnetic field, which is sensed by integrated Hall IC and converted into proportional voltage. Applications include motor control, load...
