HE84760
HE80000 SERIES
Voltage charge pump:
The LVL2 is then pumped to LVL5 based on the bias setting of MO_LBSR[3..0].
The formula for LVL5 is:
August 15, 2003
This specification is subject to change without notice. Please contact sales person for the latest version before use.

V1.2
LVL5 = LVL2 / 2 x (1/Bias)
The potential difference between bias voltages LVL1 ~ LVL5 is determined by the bias settings, too.

For example, if the bias setting is 1/7 bias and LVL2 is 2 volts, the LVL5 will be pumped to 7 volts when
the load is light.

Please note that external connections of charge pump capacitors must be made according to the bias
setting, too. Please use the following figure as reference when designing application circuit and LVL5
must be lower than 8.5 volts to prevent chip from breaking down.
