Figure 9. Lossless Inductor Sense
Set the RC time constant to be 1.1 to 1.2 times the
inductor time constant (L/DCR). Select C1 to be in the
0.1μF to 0.47μF range, and then calculate R1 from:
parallel with R2 to aid in short-circuit recovery. Set C3
equal to C1. Finally, it may be helpful to add a 100pF
(C2) capacitor immediately across the CSP_ and CSN_
inputs to minimize high-frequency noise pick-up at the
R 1 [ k ? ] =
1 . 2 × L [ μ H ]
DCR [ m ? ] × C 1 [ μ F ]
IC in some applications.
For current-sense resistors that have a noticeable
inductance component, use lossless inductor sense
In some applications, it may be useful to add a resistor
(R2 in Figure 9) in series with the CSN_ connection to
minimize input offset error. Set R2 equal to R1. It may
also prove useful to add capacitor C3 (Figure 9) in
Table 3. Current-Sense Configurations
implementation (and design procedure). See Figure 10.
Table 3 highlights the tradeoffs of each current-sense
method.
