DRV10 Electrical connections

Pin description

  • VCC (pin 1): Power supply input. Maximum supply voltage is 36 V. Minimum supply voltage is $V_{\mathrm{min}} = I_{\mathrm{laser}} \times 10 \;\Omega + 1.5 \;\mathrm{V} + V_{\mathrm{laser}}$.

  • EN (pin 2): Enable pin. Connect to VCC or GND to enable or disable the laser current. Do not leave this pin floating.

  • GND (pins 3, 6 and 7): Ground

  • ILIM (pin 4): Connect a resistor between ILIM and GND to set the current limit. Current limit is defined by $I_{\mathrm{lim}} = 200 \;\mathrm{mA} \times 750 \;\Omega / R_{\mathrm{LIM}}$. If the current limit functionnality is not needed, tie this pin to GND.

  • RSET (pin 5): Connect a resistor between RSET and LD+ to set the laser current. Laser current is defined by $I_{\mathrm{laser}} = 200 \;\mathrm{mA} \times R_{\mathrm{SET}} / 10 \;\mathrm{k}\Omega$.

  • LD+ (pin 8): Laser anode pin. Connect the laser anode to LD+ and the laser cathode to GND. The DRV10 will not work with anode grounded lasers.
