Notes
1. The typical value of
I
PROP
(0)
is set by the programmed value of
CN
and the current
Irsm
set by the external resistor
RSM, where
Ibo
=
Irsm
/ 32.
Irsm
is typically 32μA.
2. The typical value of
I
PROP
(1)
is set by the value of
I
PROP
(0)
and the programmed value of
L.
3. The current output
I
PROP
is specified between 100μA and 1mA.
4. The output current is monotonic over the CN range 128-255. In standard operation CN is set at a value > 128.
5. Where Ipda depends on the value of current setting resistor on RSA pin (9). Ipda max = 250μA
