PT2509

PT2509 is a full-bridge driver with build-in driving pattern for the swing head motor application.

It integrates the over temperature protection, short-circuit protection, and under voltage protection. With one EN control pin, the PT2509 will deliver 50Hz PWM waveform to drive the AC synchronous motor. Besides the 50Hz pattern, a clock signal can also feed to EN pin to operate with required frequency. PT2509 with package in SOP8.
