Claim Text:
1. An implantable medical device, comprising: a neural stimulator configured to deliver a neurostimulation therapy with a neural stimulation pulse frequency, wherein a dose of the neurostimulation therapy is provided by a number of neurostimulation pulses over a period of time, wherein the neural stimulator includes a clock with an oscillator, a hardware state machine operationally connected to the clock to provide pulse timing control signals, and pulse circuitry configured to receive the timing control signals and deliver neurostimulation pulses with a pulse frequency controlled using the timing control signals, the pulse circuitry including a frequency output limiter configured to avoid excessive charge delivery, wherein the frequency output limiter is configured to block a pulse from being issued only for a limited period of time after a preceding pulse, and thereby allow a subsequent pulse after the limited period of time.
