Available in space saving packages with minimized thermal resistance due to exposed pads, the TSB582 is a dual operational amplifier with embedded thermal shutdown and output current limiter for both industrial and automotive applications.

In closed-loop motor control systems a preferred way to read out the shaft’s angular position is the rotary resolver. Resolvers can be found in various applications, from light industrial to heavy duty, such as: servo motor feedback, oil and gas production, jet engine fuel systems, aircraft flight surface actuators, communication position systems, steering wheels or vehicle control systems.

Since the primary winding is typically powered through a rotary transformer, no brushes or rings are needed. This increases the overall reliability and robustness of the resolver and makes it perfectly suitable for harsh environments with varying temperature and in oily, dusty, or humid surroundings.

The TSB582 was originally designed to manage the power amplification to pilot the primary winding of a resolver device. Thanks to a wide supply voltage range (4 to 36V) the TSB582 is also an excellent fit for power demanding applications like: AC and DC power sources, valve drivers, line drivers, LED drivers and servo drivers.
