درایور موتور HG7881
Description :
HG7881C is a DC motor control and drive the design of the power
amplifier application specific integrated circuit devices, The
discrete circuitry integrated into the 1C chip, To reduce the cost
of external devices, Improve machine reliability. The chip has a
good resistance; Two output Pin can directly drive the motor
forward and backward movement, It has a large current drive
capability, At the same time, it has a low output saturation
voltage and quiescent current; Built-in clamp diode to reverse
the impact of the release of inductive load current, It in the
driving relays, DC motors, stepper motors or control the use of
switching power safe and reliably. HG7881C are widely used in
motor drive toy cars, remote-controlled aircraft motor drive,
automatic valve motor drive, electromagnetic lock drive, digital
camera, camera motors, precision instruments and other
circuits
Features :
- Quiescent current is less than 2pA
- Low no-load operating current: 15±5 mA
- Wide supply voltage range2.4V~iov
- Built-in clamp-diode
- Emergency-stop function (braking function when both inputs are high, "11" protection)
