LB1948MC: Motor Driver, Forward / Reverse, Low Saturation Voltage, 12 V
The LB1948MC is a two-channel low saturation voltage forward/reverse motor driver IC. It is optimal for motor drive in 12V system products and can drive either two DC motors, one DC motor using parallel connection, or a two-phase bipolar stepping motor with 1-2 phase excitation mode drive.
特性- 20 V max operating voltage
- Zero current drawn in standby mode
- Braking function
- Built-in spark killer diode
- Built-in thermal shutdown circuit
- Miniature package: MFP-10SK (6.2mm 5.0mm)
- Low saturation voltage: VO(sat) = 0.5V (typical) at IO = 400mA
- Supports parallel connection: IO max = 1.6A, VO(sat) = 0.6V (typical) at IO = 800mA
