Peripheral Integrated Circuits
Complimentary Products for NVE's GMR Sensors
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 200mA 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 (2.5mm X 2.5mm), 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.

Description:
The DB series signal processing ICs are designed to take a digital input from a sensor
element, and provide a high current switched output corresponding with the sensor input.
These parts function as the "front end" of a complete sensor assembly, and include
protection against short circuits and high voltage transients from capacitive and inductive
loads. The parts also feature thermal shutdown circuitry and reverse battery protection.
They provide a regulated output voltage for the sensor and other components in the
assembly, and an LED driver to indicate an "ON" condition.
Two different part numbers are offered, the DB001-00 and the DB002-02. The
DB001-00 is designed to work with NVE's AD9xx short circuit protected GMR switch
products. Together, these two ICs form the bulk of the signal processing required for
pneumatic cylinder position sensing electronics. Using these two ICs, the end user only
requires a few capacitors and an LED in order to implement the complete sensor
assembly circuit. In addition, both the AD9xx part and the DD001-00 part come in
MSOP8 packages, so that the customer can implement the complete design on an
extremely small PCB.
The DB002-02 uses the larger SOIC8 package, and is designed to work with NVE's
AD1xx GMR Switch products, as well as any other current sourcing or CMOS/TTL
digital output sensor element, such as an inductive sensor or a photo sensor. For size
critical applications, both the DB001-00 and DB002-02 are available in die form.
