Description
The OHOSOU contains a monolithic integrated circuit which incorporates a Hall element, a linear amplifier, and . Schmitt trigger on a single silicon chip. Functional Block Diagram Included on-chip is a bandgap voltage regulator to allow operation with a wide range of supply voltages. The device features logic level output and provides up to 30 mA of sink current. This allows * direct driving of more than 10 TTL loads oe or any standard logic family using power © supplies ranging from 4.5 to 24 volts. Output amplitude is constant at switching frequencies from DC to over [ec} 200 kHz. fH oureut The OHO90U is a high performance (uy > {| device capable of operation from -40° C [| to +150° C. Stability of the magnetic operate and release points is excellent over this entire temperature range. @ srouro Package size has been kept to minimum, providing an advantage in applications where space is limited.
