1 / 80 page  This is information on a product in full production. October 2013 DocID025414 Rev 1 1/80 L9374LF Four channel valve driver Datasheet - production data Features Four protected low-side drivers with diagnostics – Two 140 mΩ PWM controlled outputs (Q1 & Q2) – Two 250 m current controlled outputs with 6 % accuracy (Q3 & Q4) All outputs with 35 V Zener Clamp Programmable output timer Clock monitor Integrated recirculation diodes 16 bit serial peripheral interface, up to 5 MHz with diagnosis Battery compatible supply voltage Detailed load diagnosis – Over load protection – Open load (off-state) – Undercurrent – Undervoltage – Temperature warning and shutdown – Power or signal GND loss – Freewheeling diode loss – Silent valve driver test Description The L9374LF is a SPI (serial peripheral interface) controlled four channel low side driver with integrated recirculation diodes. The output duty cycle (all channels) / current regulation level (Q3 & Q4 only) can be programmed individually. It is possible to program two consecutive output duty cycles or target currents per channel as well as an individual duration time for each channel actuation. . PowerSO-36 Table 1.
