Additional Infomation About Product

L9349-LF Quad intelligent power low side switch Four low-side output driver with protection diagnostics designed as a conventional switch 2 channels with 5 A output current capability and r = 0.2 typ. ON 2 channels with 3 A output current capability and r = 0.3 typ. ON Integrated 60 V Zener diodes output clamping PowerSO-20 structure Output slope control Short circuit protection The device is equipped with an integrated Zener Open load detection in ON and OFF condition diodes clamp for fast inductive load current Load bypass detection recirculation. This structure limits the output Overload disable voltage during the recirculation phase to 50V. Signal and power ground loss shutdown The device is self-protected against short circuit Selective overtemperature shutdown at the outputs and overtemperature. Electrostatic discharge (ESD) protection For the real time error diagnosis, the voltage and the current of the outputs are compared with internally fixed thresholds to recognize open load Description in OFF and ON conditions. The L9349 is a monolithic IC designed to drive The output voltages are also compared with each inductive loads in low side configurations like other in OFF condition with a fixed offset, in order hydraulic valves used in ABS systems. to recognize load bypasses. Particular care has been taken to protect the If the over load current threshold is exceeded, the device against failures, to avoid electromagnetic output current will be limited internally during the interferences and to offer extensive real time diagnostic overload delay switch-off time. diagnostics. All four channels are monitored with a status The internal pull down current source at the output. The diagnostic output level in connection ENable and INput pins assures, that the device is with different enable and input conditions allows it switched off, in case of open input conditions. to recognize the different fail states. An output voltage slope limitation is implemented to reduce the EMI. Table 1. Device summary (1) Order code Package Packing L9349-LF PowerSO-20 Tray L9349TR-LF PowerSO-20 Tape and reel 1.
