STSPIN250 Low voltage brush DC motor driver Datasheet - production data Description The STSPIN250 is a single brush DC motor driver integrating a low R power stage in a small ds(ON) VFQFPN 3 x 3 mm package. The full-bridge implements a PWM current controller with fixed OFF time. The device is designed to operate in battery- powered scenarios and can be forced in a zero- consumption state allowing a significant increase in battery life. Features The device offers a complete set of protection Operating voltage from 1.8 to 10 V features including overcurrent, overtemperature Maximum output current 2.6 A with OUTAx and short-circuit protection. rms paralled to OUTBx R HS + LS = 0.2 typ. DS(ON) Current control with programmable off-time Full protection set Non-dissipative overcurrent protection Short-circuit protection Thermal shutdown Energy saving and long battery life with standby consumption less than 80 nA Applications Battery-powered DC motor applications such as: Toys Portable printers Robotics Point of sales (POS) devices Portable medical equipment Healthcare and wellness devices (shavers and toothbrushes) November 2016 DocID029872 Rev 2 1/26 This is information on a product in full production. www.st.comContents STSPIN250 Contents 1 Block diagram 5 2 Electrical data 6 2.1 Absolute maximum ratings . 6 2.2 Recommended operating conditions . 6 2.3 Thermal data . 7 2.4 ESD protections . 7 3 Electrical characteristics . 8 4 Pin description 10 5 Typical applications 12 6 Device description . 13 6.1 Standby and power-up . 13 6.2 Motor driving . 13 6.3 PWM current control . 15 TOFF adjustment 17 6.4 Overcurrent and short-circuit protections . 18 6.5 Thermal shutdown 20 7 Graphs . 21 8 Package information 23 8.1 VFQFPN 3 x 3 x 1.0- 16L package information 23 9 Ordering information . 25 10 Revision history . 25 2/26 DocID029872 Rev 2
