14 ECLP External 

current limit 

peak 

External voltage scales down the rated value. 
Voltage range: 0 V to 3.75 V (3.75 V = rated Ip) 
Refer to Section 4.2. 

15 LMRET Latch  Mode 

return 

Return for Latch Mode signals. 

16 GAIN Current gain 

change 

Shorting this pin to LMRET pin (J1/15) reduces  
the proportional gain of the current loop by 70%. 

17 HARET Hall  supply 

voltage return 

Return used only for Hall supply.
