Figure 11. Current Shift Model

Current Limit Shift Point
Comparator U1A should switch when the non-inverting input is equal to the 2.5-V reference on the
inverting input, or when the voltage applied to V_DC is equal to the selected switch point and the
voltage dropped across R36 is 2.5V. In this example, the change should occur when V_DC= 14.0V.
Equation 1.
(The nearest standard 1% value is 9.01 k
.)
Comparator U1A will pull its output low when V_DC falls below 14.0V, which will effectively put
R33 in parallel with R14.
When power is initially applied to the circuit, C18 charges up to 2.5V through R20. This slowly
rising voltage is applied to the base of the current source, Q1. The voltage on R14 is approximately
2.5V minus the base-emitter drop of about 0.7V (at 25°C): V
(R14)
≈
1.8V. Q1 is a 2N2222A with a
moderate
β
of about 100. Therefore, the current through R13 is approximately equal to the current
through R14.
The charging of C18, provides a small increment of delay as U1 will not allow R4 to pull up the
Gate of M3 until Q1 has pulled the non-inverting input of U1 down slightly.
The voltage developed across R1 is a function of the load.
