LOW INRUSH CIRCUIT FOR POWER UP AND DEEP POWER DOWN EXIT

Systems, methods, and devices for providing power to low energy circuits include inrush circuits. Devices include a regulator that includes at least one driver device configured to generate a first current associated with a load comprising a low energy integrated circuit. Devices also include a bias generator configured to generate a second current to charge a load capacitor coupled with a power terminal of the low energy integrated circuit. Devices further include an enable circuit configured to enable the bias generator and disable the regulator responsive to a load voltage being below a threshold voltage, and further configured to enable the regulator to generate the first current and disable the bias generator responsive to the load voltage being above the threshold voltage. 用于向低能量电路提供功率的系统、方法和设备，包括涌流电路。设备包括调节器，该调节器包括至少一个驱动器器件，该至少一个驱动器器件被配置成生成与包括低能量集成电路的负载相关联的第一电流。设备还包括偏置生成器，该偏置生成器被配置成生成第二电流，用于对与低能量集成电路的电源端子耦合的负载电容器充电。设备还包括启动电路，该启动电路被配置成响应于负载电压低于阈值电压，启动偏置生成器并禁用调节器，并且还被配置成响应于负载电压高于阈值电压，启动调节器来生成第一电流并禁用偏置生成器
