Programmable Outputs
dropout (LDO) regulators provided camera module core power. Each least 100mA available load current with ±3.5% accuracy. minimum current limit 200mA, outputs greater than 100mA possible somewhat reduced accuracy. capacitor should used bypass capacitor each output reduce noise ensure stability. addition, recommended that minimum 22nF capacitor connected from ground minimize noise achieve optimum power supply rejection. larger capacitor used this function, expense increasing turnon time. Capacitors with ceramic dielectric strongly recommended their superior temperature voltage characteristics. capacitors should used their temperature coefficients make them unsuitable this application.
Protection Features
SC622A provides several protection features safeguard device from catastrophic failures. These features include:
Output Open Circuit Protection Over-Temperature Protection Charge Pump Output Current Limit Current Limit Float Detection
Shutdown State
device disabled when low. registers reset default condition when low.
Output Open Circuit Protection Over-Voltage Protection (OVP) provided VOUT prevent charge pump from producing excessively high output voltage. event open circuit VOUT, charge pump runs open loop voltage rises limit. operation hysteretic, meaning charge pump will momentarily turn until VOUT sufficiently reduced. maximum threshold 6.0V, allowing ceramic output capacitor rated 6.3V with fear over-voltage damage. Over-Temperature Protection Over-Temperature (OT) protection circuit helps prevent device from overheating experiencing catastrophic failure. When junction temperature exceeds 160°C, device goes into thermal shutdown with outputs disabled until junction temperature reduced. register information retained during thermal shutdown.
Sleep Mode
When off, sleep mode activated. This reduced current mode that helps minimize overall current consumption turning clock charge pump while continuing monitor serial interface commands. Both LDOs powered while sleep mode.

Place bypass decoupling capacitors CIN, COUT, CLDO1, CLDO2, CBYP close device possible. charge pump current passes through VIN, VOUT, bucket capacitor connection pins. Ensure that connections these pins make wide traces that resistive drop each connection minimized. thermal should connected ground plane using multiple vias ensure proper thermal connection optimal heat transfer.
Make ground connections solid ground plane shown example layout (Figure ground layer feasible, following groupings should connected: PGND CIN, COUT AGND Ground Pad, CLDO1, CLDO2, CBYP ground plane available, PGND AGND should routed back negative battery terminal separate signals using thick traces. Joining ground returns terminal prevents large pulsed return currents from mixing with low-noise return currents LDOs. Both output traces should made wide possible minimize resistive losses.
