XC6121C546MR-G

The XC6121C546MR-G is a versatile battery-operated, low power-consuming, high-performance Supervisory IC (Application Specific IC) designed specifically for the cellular and embedded (or Internet of Things) segments. This device incorporates a wide-range of features and functions, including voltage detection and monitoring, supply monitoring and supervision, auto-charging, and digital threshold sensing.

Application Field and Working Principle

The XC6121C546MR-G provides a versatile solution for the primary and secondary system supervisors needed on power-dependent cellular and embedded systems. The device offers a wide range of power management options, including voltage monitoring and detection, supply monitor and supervision, auto-charging and digital threshold sensing. With varying functional loads, the XC6121C546MR-G helps meet the low power demands of mobile and embedded applications and helps extend battery life.

The XC6121C546MR-G is specifically designed to cover a wide range of voltage thresholds, allowing it to be used in product designs as a single device supervisor in an application powered by 2.7 V to 5.5 V. The device employs an internal digital comparator which can monitor either its single VCC supply or an external supply ranging in voltage from 2.7 V to 5.5 V. This allows it to provide system supervisors, reset timers and power source detection with true fail-safe capability.

The device offers a wide range of power management options, battery protection and autosense charging. It supports multiple reset modes and allows for complete configuration of the reset interval timing and delay. It also supports programmable UVLO thresholds and fault tolerance thresholds. Additionally, the XC6121C546MR-G has an auto-sense charging feature, which allows it to detect the the presence of an active battery and to initiate a charging cycle when needed. This helps extend battery life and ensures optimal system runtime.
