PCA9460 Datasheet | NXP Semiconductors

description The PCA9460 is a single chip Power Management IC (PMIC) designed to support ultra-low-power applications where standby power and overall power consumption of power management IC is critical. The PCA9460 is designed to be paired with i.MX 8ULP processor which enables such key applications. It provides power supply solutions for low power wearable application where size and efficiency are critical. The PCA9460 es equipped with four buck regulators, five LDOs and additional load switches. This design offers the most flexible configuration for i.MX 8ULP or other processors to enable the ultra-low-power system design. Each buck regulator has been designed with ultra-low Iq current to reduce standby current. Two buck regulators support smart Dynamic Voltage Scaling (DVS), which allows the system designed to set the right voltage on the processors the PCA9460 is powering. This process minimize power consumption that is controlled through the PMIC_STBY_REQ pin or MODE[2:0] pins. Five LDOs have 300 n A low quiescent current. One LDO is available for SNVS core power supply, one 250 m A LDO is to regulate to low output voltage from buck regulator output. Three 250 m A LDOs supply power to the processor and peripheral devices. Four 150 mΩ load switches switch power for peripheral devices. These switches can be configured as an LED driver with two different blink modes. The PCA9460 is offered in a 42-bump wafer-level CSP package, 2.86 mm x 2.46 mm, 0.4 mm pitch. 2 Features and benefits Ultra-low-power system design for long battery life or green offline performance using: - Four buck regulators - Two 1 A buck regulators - Two 1 A buck regulator with DVS - Low Iq (1.5 μA at low power mode, 5.5 μA at normal mode) - Five linear regulators - One 250 m A NMOS LDO - Three 250 m A PMOS LDO - 10 m A SNVS LDO - Built-in active discharge resistor - Four Load Switches with active discharge resistor to allow easy connect/disconnect of multiple system rails - 150 mΩ Rdson - ON/OFF...
