L2293Q STMicroelectronics

L2293Q Push-pull four channel driver with diodes Features 600 mA output current capability per channel 1.2 A peak output current (non repetitive) per channel Enable facility VFQFPN 5 mm x 5 mm 32L Overtemperature protection Logical 0 input voltage up to 1.5 V (high noise To simplify use as two bridges each pair of immunity) channels is equipped with an enable input. A separate supply input is provided for the logic, Internal clamp diodes allowing operation at a lower voltage and internal clamp diodes are included. Description This device is suitable for use in switching The device is a monolithic integrated high voltage, applications at frequencies up to 50 kHz. high current four channel driver designed to The L2293Q is assembled in a VFQFPN-32L 5x5 accept standard DTL or TTL logic levels and drive package which has exposed pad available for inductive loads (such as relays solenoides, DC heatsinking. and stepping motors) and switching power transistors.
