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.
主要特性
- Four protected low-side drivers with diagnostics
- Two 140 mΩPWM controlled outputs(Q1 & Q2)
- Two 250 mΩ 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
- Four protected low-side drivers with diagnostics
