Description:
The DB002 series power switch IC is designed to take a digital input from a sensor element 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 part also features 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.
The DB002 is available in the SOIC8 package (p/n DB002-02), as well as in die form (p/n DB002-01) .
It is designed to work with NVE’s AD1xx GMR Switch products, or any other current sourcing or
CMOS/TTL digital output sensor element such as an inductive sensor or a photo sensor.
