Symbol
Parameter
Conditions
Minimum Typical Maximum
t_fault Laser fault time - from fault condition From occurrence of fault condition or when
to assertion of FAIL
Supply_OK is beyond specified range
t_reset DIS time to start reset
DIS pulse width required to initialize safety
circuitry or reset a latched fault
tVCC_OK Supply_OK delay time
Delay between Supply_OK condition and when
10
outputs are enabled
t_onBM DIS negate (turn-on) time during
burst-mode operation
IMOD > 20mA; outputs DC coupled (5V
operation)(4)
t_offBM DIS assert (turn-off) time during
burst-mode operation
IMOD > 20mA; outputs DC coupled (5V
operation)
NOTES:
1. With CAPC < 2.2nF
2. User-adjustable. Specifications reflect timing with no external RESET capacitor.
3. With < 1nF capacitor from RESET pin to ground.
4. Imod >12mA
