This device has a discharge switch (Q_Discharge2/4) for the CH2/4 output capacitor. The typical ON resistance
at the discharge switch is 1 k
. The discharge switch is activated when XSLEEP turns low. For CH4 only, the
switch is also activated when ENAFE turns low. After output voltage reaches approximately 0.5 V, the discharge
switch turns OFF and VOUT2/VOUT4 is changed into high impedance. The output voltage is programmable from 2.5
V to 3.6 V (for CH2) or from 2.2 V to 3.6 V (for CH4) to use the feedback loop sensed by the external
resistances. The output voltage is calculated by Equation 4. The block diagram is shown in Figure 5.
VOUT = (1 + R2/R1) × 0.6 [V]

Where:
VOUT = Output voltage [V]
R1, R2 = Feedback resistance (see Figure 5)
