PQ6206Q
High-Performance ASIL-B Rated PMIC with Buck Converters and LDO for Automotive Camera Module
The PQ6206Q is a high-performance Power Management IC (PMIC) for automotive camera modules. It integrates a high-voltage buck converter for a primary regulator, dual low-voltage buck converters and a low noise LDO for secondary regulators.
The devices feature a 2.2MHz fixed-frequency PWM mode for better noise immunity and load-transient performance. The high-frequency operation allows for the use of all ceramic capacitors and minimizes external components. The programmable spread-spectrum frequency modulation minimizes radiated electromagnetic emissions. Integrated low-RDS(ON) switches improve efficiency at heavy loads and make layout simpler than discrete solutions.
I2C digital interface allows for application flexibility. Output voltage, power sequence, and protection thresholds can all be adjusted through the interface. Fault status can also be monitored. Protection features include undervoltage lockout (UVLO), over current protection (OCP), over voltage protection (OVP), under voltage protection (UVP) and thermal shutdown (TSD).
The PQ6206Q supports applications with a high automotive safety integrity level up to ASIL-B. Functional safety features such as an analog built-in self-texting (ABIST), diagnostics, a nRESET and a nINT output pin are all included. It is developed under Functional Safety Product Development process, which has been independently certified to meet ISO26262 guidelines.
The PQ6206Q is available in 22-pin 3mm x 3.5mm MIS packages.
