Product data sheet
1 General description
The PCA9450 is a single chip Power Management IC (PMIC) specifically designed to
support i.MX 8M family processor in both 1 cell Li-Ion and Li-polymer battery portable
application and 5 V adapter non-portable applications. It supports various memory types
(DDR4/LPDDR4/DDR3L, etc.) via system UBOOT configuration, which does not require
hardware change.
The device provides six high efficiency step-down regulators, five LDOs, one 400 mA
load switch, 2-channel level translator and 32.768 kHz crystal oscillator driver.
Three buck regulators support Dynamic Voltage Scaling (DVS) feature along with
programmable ramping up and down time and those buck regulators support remote
sense to compensate IR drop to load from buck regulator. This device is characterized
across -40 °C to 105 °C ambient temperature range.
Six step-down regulators are designed to provide power for i.MX 8M application
processor and DRAM memory. Two LDOs, LDO1 and LDO2, feature very low quiescent
current to provide power for Secure Non-Volatile Storage (SNVS) since these LDOs are
always ON when input voltage is valid.
PCA9450 integrates logic translator which is a 2-bit, dual supply translating transceiver
with auto direction sensing. It enables bidirectional voltage level translation. It can be
used as I2C level translator. 400 mA load switch is to supply 3.3 V power supply to SD
card, which has internal discharge resistor.
PCA9450 has three versions: PCA9450A is companion PMIC for (i.MX 8M Mini),
PCA9450B is companion PMIC for i.MX 8M Nano and PCA9450C is companion PMIC
for i.MX 8M Plus.
The PCA9450 is offered in 56-pin HVQFN package, 7 mm x 7 mm, 0.4 mm pitch.
