SPECIFICATIONS
Typical (typ) is given for VS = VS_DRV = 3.3 V ± 5%; VS ≤ VCP ≤ 5.25 V; TA = 25°C; RSET = 4.12 kΩ; CPRSET = 5.1 kΩ, unless otherwise
noted. Minimum (min) and maximum (max) values are given over full VS and TA (−40°C to +85°C) variation.

kΩ Sets internal CP current range, nominally 4.8 mA (CP_lsb = 600 μA); actual
current can be calculated by: CP_lsb = 3.06/CPRSET; connect to ground
