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 standalone 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.

Output Driver for Sensor Assemblies
Usable with Magnetic, Inductive, and Photo Sensors
Description:
The DB001-00 signal processing IC is designed to take the digital input signal from NVE’s AD9xx
GMR Switch and provide a high current switched output corresponding with the sensor input. The part
functions as the “front end” of a complete sensor assembly and includes protection against short
circuits and high voltage transients from capacitive and inductive loads. The parts also feature thermal
shutdown circuitry and reverse battery protection. It provides a regulated output voltage for the sensor
and other components in the assembly and an LED driver to indicate an “ON” condition.
Together, the AD9xx GMR Switch and the DB001-00 signal processing IC 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 DB001-00 part come in MSOP8 packages, so that the
customer can implement the complete design on an extremely small PCB.
If ultra-miniaturization is desired, the DB001 part can be obtained in die form for COB (Chip On
Board) or flip-chip assembly.

Notes:
1.
Power dissipation rating for TDFN6 package in free air is 320°C/Watt. Soldering the package to a PCB, including the die
attach paddle, improves temperature performance substantially. The input voltage and output current are limited by thermal
power dissipation at the package.
2.
Due to package size, TDFN6 package has a three-letter code to designate part type.

Excellent Temperature and Voltage Performance

Description:
The DD-Series signal processing IC is designed to take an analog, sinusoidal input signal such as that
provided by NVE’s ABL-Series sensors and convert it to a two wire, current modulated digital output.
Inputs as small as 2 mV peak-to-peak can be provided to the IC, along with large signal offsets. The
DD001-12 part will provide a 50% duty cycle digital output signal.
The DD001-12 part contains a voltage regulator circuit, programmable amplifier, offset detection and
correction circuitry, and an EEPROM for setting gain and current levels. The voltage regulator output
(3.3V) is used to power the external sensor element, which should be connected between VREG and
VGND. Nominal current levels for the current modulated output are 3 mA and 10 mA. These can be
factory programmed to different levels for specific customer requirements.
Using the DD-Series signal processing IC allows the user to put the sensor element, which can very
small in a remote location, and pipe the signals from the sensor to the DD001-12 for digitizing
purposes. In addition, if two phase shifted sensor outputs are available (such as with the ABL014-00,
ABL015-00, and ABL015-00sensors), two DD001-12 parts can be used to provide two phase shifted
digital signals, for the purpose of detecting the direction of the gear tooth or encoder wheel.
The two-wire output of the DD001-12 can be easily converted to a three-wire current-sinking output
with the circuit shown in the GT Sensor applications section.
