NXP Semiconductors PCA9460 13-Channel Power Management ICs (PMICs)
NXP Semiconductors PCA9460 13-Channel Power Management ICs (PMICs) are single-chip PMICs designed to support ultra-low-power applications where the PMIC's standby power and overall power consumption are critical. The PCA9460 is designed to be paired with the i.MX 8ULP processor, which enables such key applications. It provides power supply solutions for low-power wearable applications where size and efficiency are critical.
The PCA9460 has 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 to set the correct voltage for the processors the PCA9460 is powering. This process minimizes power consumption controlled through the PMIC_STBY_REQ pin or MODE[2:0] pins. Five LDOs have 300nA low quiescent current. One LDO is available for the SNVS core power supply; one 250mA LDO regulates low output voltage from buck regulator output. Three 250mA LDOs supply power to the processor and peripheral devices. Four 150mΩ load switches switch power for peripheral devices. These switches can be configured as an LED driver with two different blink modes.
The NXP Semiconductors PCA9460 is offered in a 42-bump wafer-level CSP package, 2.86mm x 2.46mm, 0.4mm pitch.
