Frequently Asked Questions

What input voltage range do AutoChips PMICs support?

AutoChips automotive PMICs support wide input voltage ranges to accommodate vehicle battery variations and transient conditions. Standard devices support 3.5V to 40V input, covering normal battery voltage (12V) and load dump conditions up to 40V. Some devices support up to 60V for heavy-duty vehicle applications. The wide input range ensures reliable operation during cold cranking (voltage dips to 3.5V) and load dump transients (voltage spikes to 40V) per ISO 7637-2 automotive electrical transient immunity standard.

Select PMICs with input voltage range covering your worst-case vehicle electrical conditions.

What protection features are included in AutoChips PMICs?

AutoChips automotive PMICs include comprehensive protection features for reliable vehicle operation. Standard protections include over-voltage protection (OVP) for load dump conditions, over-current protection (OCP) with current limiting, over-temperature protection (OTP) with thermal shutdown, and reverse polarity protection. Additional automotive-specific features include under-voltage lockout (UVLO) for safe startup, soft-start to limit inrush current, and power-good indicators for system monitoring. These protections ensure reliable operation in harsh automotive electrical environments.

All AutoChips PMICs include essential automotive protections. Contact LiTong for specific protection requirements.

What is the quiescent current of AutoChips PMICs?

AutoChips automotive PMICs feature low quiescent current to minimize standby power consumption in vehicle applications. Typical LDO regulators have quiescent current of 20-50 microamps during normal operation. For always-on circuits in standby mode, some devices feature ultra-low quiescent current below 10 microamps. The low quiescent current is essential for reducing battery drain when the vehicle is parked, extending battery life and ensuring reliable starting after extended parking periods.

Select PMICs with low quiescent current for always-on circuits to minimize standby battery drain.

Do AutoChips PMICs support functional safety applications?

Yes, AutoChips offers PMICs with functional safety features for ASIL-compliant automotive systems. Safety features include voltage monitoring with window watchdog, independent safety monitoring outputs, and diagnostic capabilities for fault detection. Some devices include dual-channel regulators for redundant power supply to safety-critical MCUs. The PMICs are designed to work with AutoChips ASIL-D capable MCUs to provide complete safety system solutions. Safety documentation including FMEDA and safety manuals are available for ISO 26262 compliance.

Contact LiTong for safety PMIC recommendations for ASIL-compliant applications.

What packages are available for AutoChips PMICs?

AutoChips automotive PMICs are available in packages suitable for automotive applications and manufacturing processes. Standard packages include SOP-8 and SOP-16 for through-hole and surface-mount assembly, TSSOP-16 and TSSOP-20 for compact designs, and QFN-32 for high-density applications. All packages are AEC-Q100 qualified and support lead-free (RoHS compliant) manufacturing. Package selection depends on thermal requirements, pin count, and PCB space constraints.
