Notes
3. The circuit is defined with resistors RSMA and RSC connected from pins RSMA and RSC to VSSSA but in most practical applications all VSS pins
will be connected to a ground plane so RSMA and RSC should then also be connected to this ground plane.
4. The charge pump currents are specified to this accuracy when the relevant output pin is at a potential of VDD/2 and with RSMA = 39 kΩ, CN
= 200, L= 1, K = 5, RSC = 19 kΩ. The nominal value is set by external resistors and by programming registers, as defined in Table 6. Tolerances
in the internal Bandgap voltage and bias circuits are within the limits given for IRSMA and IRSC, the scaling accuracy of the multiplying DAC’s
is within these limits given for Iprop(0), Iprop(1), Iint, Icomp(0), Icomp(1), Icomp(2), and auxil.
5. The Auxiliary charge pump output voltage is referred to as VPDA and the output current IAUX is the Up or Down current measured when
VPDA = VDD/2.
The conditions for the variation limits for the Up current are:
either
or
IAUX = 128 or 256 µA
IAUX = 512 µA
and
and
0 < VPDA < VDD – 0·5 V
0 < VPDA < VDD – 0·65 V
The conditions for the variation limits for the Down current are:
either
or
IAUX = 128 or 256 µA
IAUX = 512 µA
and
and
0·5 V < VPDA < VDD
0·65 V < VPDA < VDD
6. The Main charge pump output voltage at pin PDP is referred to as VPDP and at pin PDI as VPDI. The output currents IMAIN and IINTEGRAL are the
up or down current Iprop(0), Iprop(1) or Iint measured when VPDP or VDPI = VDD/2.
The conditions for the variation limits for the Up current are :
IMAIN = 100 to 1000 µA or IINTEGRAL = 1 to 5 mA and 0 < VPDP < VDD – 0·45 V
The conditions for the variation limits for the Down current are:
IMAIN = 100 to 1000 µA or IINTEGRAL = 1 to 5 mA and 0·45 V < VPDP < VDD
