LTC6820HMS#3ZZTRPBF

Specialized Overview

The LTC6820HMS#3ZZTRPBF is an isoSPI isolated communications interface IC manufactured by Analog Devices Inc. It provides bidirectional SPI communication between two isolated devices via a single twisted-pair connection, bridged by a pulse transformer. The device operates with a VDD supply voltage range of 2.7V to 5.5V and supports logic levels from 1.7V to 5.5V on the VDDS pin. It achieves data rates up to 1Mbps and features an ultralow idle current of 2µA. The component is qualified under AEC-Q100 standards for automotive applications and functions within a specified temperature range of –40°C to 125°C.

Specialized Feature Summary

• Provides galvanic isolation using standard transformers without requiring a center tap
• Configurable drive currents and comparator thresholds for optimized noise immunity or low power consumption
• Engineered for ISO26262 compliant systems with automatic wake-up detection capabilities

Specialized Applications

• Automotive battery monitoring systems
• Industrial networking interfaces
• Remote sensor connections

Specialized Procurement Notes

Verify the specific ordering suffix #3ZZ indicates automotive-grade manufacturing controls required for reliability in automotive environments. Confirm that the MSOP-16 package variant matches the design requirements for the target application before finalizing procurement orders.

Specialized Selection Notes

Select this part when high-reliability automotive certification is mandatory. Ensure the system design accommodates the 125°C maximum junction temperature. Verify that the external resistor divider values correctly set the bias current and comparator thresholds for the intended cable length and impedance.

Specialized Part Context

This component belongs to the LTC6820 family of isoSPI isolated communication interfaces. The 'H' designation specifies the extended industrial temperature range of –40°C to 125°C, while the 'M' indicates the 16-lead MSOP package. The '#3ZZ' suffix denotes automotive-grade production standards.

Specialized Replacement Considerations

LTC6820IMS#3ZZTRPBF offers identical functionality but is rated for a lower operating temperature range of –40°C to 85°C.
