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 outp ut of up to 200mA is required. NVE's DB Series parts are designed to meet these requireme nts. They feature transient protection to meet rigid EMC and ESD standards, ther mal shutdown for temperature protection, reverse battery protection , a regulated voltage output, an on-chip LED driver, and short circuit protection of the current drive outp ut transistor. The DB001-00 is designed specifically to work together with NVE's AD9 xx-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 ge neric 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 immuni ty 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 sinki ng 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 AB L 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 mod ulated signal that it provides for NVE's ABL series GT Sensors.

Applications:
Output Driver for Sensor Assemblies Usable with Magnetic, Inductive, and Photo Sensors
Description:
The DB series signal processing ICs are designed to take a digital input from a sensor eleme nt, 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. The y 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 pne uma tic 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 extre mel y small PCB. The DB002-02 uses the larger SOIC8 package, and is designed to work with NVE's AD1 xx 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.
