LMD18245T/NOPB, Драйвер двигателя полумостовой, 12-55 В, 3 А

Описание LMD18245T/NOPB The LMD18245T/NOPB is a 3A 55V DMOS Full-bridge Motor Driver incorporates all the circuit blocks required to drive and control current in a brushed type DC motor or one phase of a bipolar stepper motor. The multi-technology process used to build the device combines bipolar and CMOS control and protection circuitry with DMOS power switches on the same monolithic structure. It controls the motor current via a fixed off-time chopper technique. An all DMOS H-bridge power stage delivers continuous output currents up to 3A (6A peak) at supply voltages up to 55V. The DMOS power switches feature low RDS(ON) for high efficiency and a diode intrinsic to the DMOS body structure eliminates the discrete diodes typically required to clamp bipolar power stages. An innovative current sensing method eliminates the power loss associated with a sense resistor in series with the motor. • Internal clamp diodes • Low-loss current sensing method • Digital or analog control of motor current • TTL and CMOS compatible inputs • Thermal shutdown (outputs off) at TJ = 155°C • Over-current protection • No shoot-through currents • Green product and no Sb/Br Тип драйвера (контроллера)dmos full bridge motor driverИнтерфейсparallelВыходной ток, А3Напряжение нагрузки, В12…55Напряжение питания, В12…55Рабочая температура,°C-40…+150Корпусto-220-15Вес, г10
