L2293Q

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 ■ Overtemperature protection ■ Logical “0” input voltage up to 1.5 V (high noise immunity) ■ Internal clamp diodes Description The device is a monolithic integrated high voltage, high current four channel driver designed to accept standard DTL or TTL logic levels and drive inductive loads (such as relays solenoides, DC and stepping motors) and switching power transistors. VFQFPN 5 mm x 5 mm 32L To simplify use as two bridges each pair of channels is equipped with an enable input. A separate supply input is provided for the logic, allowing operation at a lower voltage and internal clamp diodes are included. This device is suitable for use in switching applications at frequencies up to 50 kHz. The L2293Q is assembled in a VFQFPN-32L 5x5 package which has exposed pad available for heatsinking. Figure 1.
