Frequently Asked Questions
Is PCA9451A only for i. MX 93?
PCA9451A is specifically optimized for i. MX 93 power requirements. While it may work with other processors, NXP recommends using processor-specific PMICs for optimal performance and reliability.
Use PCA9451A specifically for i. MX 93. Contact FAE for other processor recommendations.
What is the difference between industrial and consumer grades?
Industrial grade (-40°C to +105°C) is suitable for harsh environments and industrial applications. Consumer grade (-40°C to +85°C) is suitable for standard consumer electronics. Industrial grade undergoes additional testing and qualification.
Choose industrial grade for harsh environments or extended temperature needs. Consumer grade for cost-sensitive standard applications.
Does PCA9451A support both LPDDR4 and DDR3L memory?
Yes, PCA9451A supports multiple memory types including LPDDR4 and DDR3L. Different OTP variants or I2C configuration can set appropriate voltages for different memory technologies.
Verify memory voltage requirements. Configure PMIC appropriately for your memory type.
What is the typical BOM cost savings compared to discrete solutions?
PCA9451A typically reduces BOM cost by 30-40% compared to discrete power solutions by integrating multiple regulators, load switches, and sequencing logic. The optimized design for i. MX 93 eliminates unnecessary features while providing all required functionality.
Compare total BOM cost including all external components. PCA9451A offers significant savings for i. MX 93 designs.
