PLANO, Texas -- August 22, 2013

Diodes Incorporated (Nasdaq:DIOD), a leading global manufacturer and supplier
of high-quality application specific standard products within the broad
discrete, logic and analog semiconductor markets, today introduced six
high-performance Hall effect sensor switches, designed to save power in
position and proximity detection roles in a variety of consumer, home
appliance and industrial equipment. Optimized for a supply voltage range from
1.6V to 3.6V and using a hibernating clocking system to minimize power
consumption, the switches’ average supply current is typically 4.3µA at 1.8V.

The micropower Hall effect product introduction comprises the
medium-sensitivity AH1895 and high-sensitivity AH1893, AH1897 and AH1812
omnipolar switches. Also included are the programmable high-sensitivity AH1894
omnipolar switch and the AH3360, a high-sensitivity unipolar (south pole)
switch. These simple devices are offered in space-saving and low-profile
X1-DFN1216-4 (1.2mm x 1.6mm x 0.5mm) and leaded SOT553 (1.6mm x 1.6mm x 0.5mm)

All devices, with the exception of the AH1812, include an internal push-pull
output structure, which enables a reduction in external component count and a
simplification of PCB layouts. The AH1812 provides an open-drain output option
for added flexibility in system pull-up.

A chopper-stabilized design means these highly integrated devices offer
improved temperature stability, immunity to stress effects and minimal drift
across their operating temperature range of -40ºC to +85ºC. Protection against
ESD is also high at 8kV, helping to improve product robustness and simplifying
handling during manufacture.

Providing additional design flexibility, the programmable-variant AH1894
enables users to select between one of two magnetic sensitivity ranges using a
band select pin, allowing the one device to accommodate different strengths of
magnets located at different distances from the Hall sensor. Band selection
can either be hardwired or programmed electronically using an external logic
source such as a microcontroller. For further information, visit the Company’s
