Peripheral Integrated Circuits
In addition to GMR Sensor products, NVE has begun designing and manufacturing accessory products
for our sensors. These products are designed to be used with NVE’s sensors, or in some cases as stand-
alone parts, to provide higher level signal processing capabilities coupled with the robust performance
characteristics that NVE products are known for.
DB-Series Power Switch ICs – In many industrial control applications, a digital current output of up
to 200 mA is required. NVE’s DB-Series parts are designed to meet these requirements. They feature
transient protection to meet rigid EMC and ESD standards, thermal shutdown for temperature
protection, reverse battery protection, a regulated voltage output, an on-chip LED driver, and short
circuit protection of the current drive output transistor. The DB001-00 is designed specifically to work
together with NVE’s AD9xx-00 short circuit protected GMR switch to create a very small IC
combination suitable for use in miniature sensor assemblies. The DB002-02 is designed to take a
generic digital input from any source, including inductive and photo sensors, and provide the digital
current output.
DC Series Voltage Regulator ICs – These ICs are designed for use in high voltage, low current
applications. They provide a wide input voltage range, up to 60V, and are available in 3.3V and 5.0V
outputs. They feature reverse battery protection and excellent immunity to transients and noise
allowing for the reduction or elimination of filtering devices at the PCB level. They are available in the
TDFN6 package, which features a small PCB footprint (2.5 mm x 2.5 mm) and an exposed lead frame
on the back for heat sinking to the PCB. DC series voltage regulators meet 42V automotive standards.
DD-Series Signal Processing IC for Analog GT Sensors – The DD001-12 is designed to be
interfaced with an NVE ABL-Series GT Sensor to provide a digital output signal with excellent
stability characteristics. It can be located away from the sensor so that the ABL package (MSOP8 or
TDFN6) can be placed in a small remote housing, resulting in the absolute minimum size sensor
package. The DD001-12 can also be used with other sensing devices which feature a sinusoidal output,
to provide the same stable current modulated signal that it provides for NVE’s ABL-Series GT
Sensors.
