STMicroelectronics TSB582

200 mA output current with thermal shutdown and output current limiter, 3.1 MHz, 36 V, BiCMOS dual operational amplifier

The TSB582 is a unity gain stable, dual operational amplifier with high voltage and high current capability, featuring internal protections against overtemperature and current overload conditions. In addition, the TSB582 has enhanced ESD and RF noise immunity. It typically outputs up to 200 mA per channel to drive low resistance inductive loads such as angle resolvers, lineout cables and piezo actuators. The two high current output amplifiers of the TSB582 feature the advantage of driving loads directly in bridge tied mode or, connected in parallel, allow to double the output sink/source current. Additionally, the TSB582 is available in the two space-saving packages, SO8 with exposed pad and DFN8 with wettable flanks and exposed pad. Where both of them are qualified for automotive applications over a temperature range of -40 °C to +125 °C.

Available tools

STEVAL-TTM005A:

Resolver board reading for motor position estimation

The STEVAL-TTM005A is a powerful tool that has been specifically designed for developing and testing automotive motor control applications. The board ensures accurate motion sensing based on rotor position estimation with resolver feedback. This rotor position estimation allows to obtain an excellent control since zero speed, with the most advanced F.O.C. algorithms reducing any torque and speed ripple on the motor.
