Silanna SLE2001-V01 FirePower Evaluation Board
Silanna SLE2001-V01 FirePower Evaluation Board is designed to help evaluate the SL2001, an integrated laser drive system. This 800W Vertical Cavity Surface Emitting Laser (VCSEL) load evaluation board uses the SL2001 laser driver Integrated Circuit (IC). The Silanna SLE2001-V01 FirePower Evaluation Board offers a simple 800W peak power and a less than 5ns FWHM resonant flash Time-of-Flight (TOF) laser system with a wide input range of 2.8V to 24V. The design demonstrates the high peak power with a very narrow laser FWHM pulse, which can be achieved due to the high level of integration of the SL2001 controller.
Features
- Flexible architecture can provide laser FWHM pulses less than 2ns
- Dual drive outputs support peak power up to 1000W
- High charging efficiency from a single 2.8V to 24V supply
- Integrates needed blocks for charging and firing resonant mode diode lasers utilizing either EEL diodes or VCSEL arrays
- Integrated GAN/MOS drive for charging a resonant capacitor
- Inductor current control offers precise resonant capacitor energy, even with input voltage fluctuations
- <5mW system no load power consumption
- Up to 10MHz rep rate limited by temperature rise in the laser and other board components
- Dual polarity LIGHT output signal to indicate when the laser fires with extremely low jitter (time error jitter < 0.1ns)
- Minimal external components enable an extremely integrated and efficient layout
- Integrated I2C interface and non-volatile memory for output power control and fault monitoring
- 1mm x 3.5mm WLCSP package utilizing bumped die
Applications
- Laser TOF measurement systems
- Light detection and ranging (LIDAR) arrays
- Range finding
- 3D mapping
- Advanced driver-assistance systems (ADAS)
