DIMENSIONS ARE IN INCHES (MILLIMETERS) Features Operates over a broad range of supply voltages e Excellent temperature stability to operate in harsh environments e Drive capability up to 10 TTL loads Hall element, linear amplifier, and 6 Schmitt trigger on a single Hallogic silicon chip Description The OH360U contains a monolithic integrated circuit which incorporates a Hall element, a linear amplifier, a threshold amplifier, and Schmitt trigger on a single silicon chip. 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 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 200 kHz. The OH360U is a high performance 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. Package size has been kept to minimum, providing an advantage in applications where space is limited.
