SX8724
ZoomingADC for Pressure and Temperature Sensing
Charge Pump
This block generates a supply voltage able to power the analog switch drive levels on the chip.
The minimum acceptable switch supply is 3V which means that if VBATT drops below 3V then the block should
be activated to generate a voltage of 3V or above. If VBATT is greater than 3V then VBATT may be switched
straight through to the VPUMP output.
If control input bit MULT_FORCE_OFF = 1 in RegMode register then the charge pump is disabled and VBATT is
permanently connected to VPUMP.
If control input bit MULT_FORCE_ON = 1 in RegMode register then the charge pump is permanently enabled.
This overrides MULT_FORCE_OFF bit in RegMode register.
If MULT_FORCE_ON = 0 and MULT_FORCE_OFF = 0 bits in RegMode register then the charge pump will
start if VBATT drops below 3V, otherwise VBATT will be switched directly through to VPUMP.
These controls are supplied to give the user the option of fixing the charge pump state to avoid it turning off and
on when VBATT is close to 3V.
The cell will use the on-chip bandgap reference and comparator to detect when VBATT is too low. When
activated, the block will use the charge pump to boost the VBATT voltage to above 3V but with diode limiting to
ensure that the generated voltage never exceeds 0.7V above VBATT.
An external capacitor is required on VPUMP whenever the power supply is supposed to be less or drop below 3V.
This capacitor should be large enough to ensure that generated voltage is smooth enough to avoid affecting
conversion accuracy but not so large that it gives an unacceptable settling time. A recommended value is
around 2.2nF.
The block will also indicate when the pumped output voltage is sufficiently high to allow ADC conversions to be
started. This will be a simple comparison which will give a ready signal when the VPUMP output is 3V or above.
