Diodes Incorporated has introduced ‘the world’s smallest’ programmable omnipolar Hall-effect switch. The AH1892 is well suited for proximity and position detection in space-constrained portable and battery-powered products. Provided in the miniature 4-pin 0,7 x 0,7 x 0,5 mm U-WLB0707-4 package, the device is 17 times smaller than the common 3-pin TSOT packaged alternatives.
The package’s space-saving advantage is further enhanced by the switch’s integrated pull-up resistors, which simplify the external circuit layout and save more PCB space. A simple band select pin enables device sensitivity to be programmed to one of two predefined magnetic sensitivity ranges, allowing the device to be used in multiple applications with different field strengths.
Sensitivity can also be adjusted on the fly via an external logic source such as a microcontroller, whereby band can be adjusted with a simple firmware upgrade.
The AH1892’s low operating voltage supply range, from 1,6 V through 3,6 V, has been specifically optimised for portable and battery-powered applications, with normal operation consuming an average current of just 4,3 μA.
To help improve product reliability during manufacture and use, the device provides protection against electrostatic discharge to a level of 8 kV on supply and output pins. With Hall switch operating and release points highly stable over the extended temperature range from -40°C to 85°C and with a very low temperature coefficient, the IC is immune to the possibility of early or late switching effects. The device’s chopper based design also offers high resistance to RF noise and other circuit stresses.
