Sytatek SA8340
The SA8340 device is a brushed-DC motor driver for robotics, appliances, industrial equipment, and other small machines. The inputs can be pulse width modulated (PWM) to control motor speed, using a choice of current-decay modes. The SA8340 device features integrated current regulation, based on the analog input VREF and the voltage on the ISEN pin, which is proportional to motor current through an external sense resistor.| Part No. | SA8340 |

DESCRIPTION
Two logic inputs control the H-bridge driver, which consists of four N-channel MOSFETs that can control motors bidirectionally with up to 4.0-A peak current. Setting both inputs low enters a low-power sleep mode. The ability to limit current to a known level can significantly reduce the system power requirements and bulk capacitance needed to maintain stable voltage, especially for motor startup and stall conditions. The device is fully protected from faults and short circuits, including undervoltage (UVLO), overcurrent (OCP), and overtemperature (TSD). When the fault condition is removed, the device automatically resumes normal operation.FEATURES
