Overview
The L2293Q is a monolithic integrated high voltage, high current four-channel driver designed by STMicroelectronics. This device is capable of accepting standard DTL or TTL logic levels and driving inductive loads such as relays, solenoids, DC and stepping motors, and switching power transistors. It features a separate supply input for the logic, allowing operation at a lower voltage, and includes internal clamp diodes for protection. The L2293Q is assembled in a VFQFPN-32L 5x5 package with an exposed pad for heatsinking, making it suitable for switching applications at frequencies up to 50 kHz.
