Description
Positive Supply Voltage Input. Connect this pin to the 3 V supply with a 2.2 μF decoupling capacitor. Must be
electrically tied together with Pin 8 by a PCB trace.
Voltage Doubler Output. This is derived by doubling the 3 V supply. A 2.2 μF capacitor to ground is required
on this pin.
Voltage Regulator Input. The user can bypass this circuit by using the LDO_ON/OFF pin.
5 V Output. This is derived by doubling and regulating the 3 V supply. A 2.2 μF capacitor to ground is required
on this pin to stabilize the regulator.
5 V Input. This is the input to the voltage tripler and inverter charge pump circuits.
Control Logic Input. 3 V CMOS logic. A logic high selects the internal LDO for regulation of the 5 V voltage
doubler output. A logic low isolates the internal LDO from the rest of the charge pump circuits. This allows the
use of an external LDO to regulate the 5 V voltage doubler output. The output of this LDO is then fed back into
the voltage tripler and inverter circuits of the ADM8839.
Digital Input. 3 V CMOS logic. Active low shutdown control. This shuts down the timing generator and enables
the discharge circuit to dissipate the charge on the voltage outputs, thus driving them to 0 V.
Connect this pin to V CC . Must be electrically tied with Pin 1 by a PCB trace.
Connect this pin to GND. Must be electrically tied with Pin 18 by a PCB trace.
15 V Output. This is derived by tripling the 5 V regulated output. A 0.22 μF capacitor is required on this pin.
External Capacitor C3 is connected between these pins. A 0.22 μF capacitor is recommended.
External Capacitor C2 is connected between these pins. A 0.22 μF capacitor is recommended.
External Capacitor C4 is connected between these pins. A 0.22 μF capacitor is recommended.
?15 V Output. This is derived by tripling and inverting the 5 V regulated output. A 0.22 μF capacitor is required
on this pin.
Device Ground. Must be electrically tied with Pin 9 by a PCB trace.
External Capacitor C1 is connected between these pins. A 2.2 μF capacitor is recommended.
