The TimerBlox family consists of five basic parts:  the LTC6990, LTC6991, LTC6992, LTC6993 and LTC6994. In order to ensure broad application coverage across these timing functions, the five parts are offered in a total of twelve options. The LTC6992, PWM generator, is offered in four options to provide 100% modulation control, or to limit modulation control at the minimum or maximum modulation ranges. Limiting control ensures that the LTC6992 output does not stop switching, which is an important feature for applications unable to withstand a steady state signal. The LTC6993 is offered in four options to provide rising edge or falling edge triggers, and to provide retriggerable and non-retriggerable capability. Finally, the LTC6994 delay block is offered in two options for triggering on a single edge, rising or falling, or to trigger on both input signal edges.
