Power Management Integrated Circuit (PMIC) is an important component in modern electronics, allowing designers to multiplex a wide range of power supplies in a single device to reduce board size, cost and complexity. PMICs are typically employed in the power supply, data communication and on-board sensing applications.

Supervisors, a subtype of PMICs, provide full-scale protection for electronic systems, by measuring system voltage levels, monitoring temperature, shutoff power when the voltage levels exceed their limit, and other system errors. LTC2934IDC-2#TRPBF is an integrated supervisor device specifically designed to provide exact monitoring and protection in mobile, computing and communication applications.

The LTC2934IDC-2#TRPBF supervisor uses a two-wire interface to monitor two digital inputs and two thresholds (UV and OV). Both inputs and thresholds can be configured from 1.2V up to 13V in 100mV increments, thus allowing to monitor up to 10V supply range for both inputs. An adjustable reset delay is included to delay the activation of the reset pulse to allow more time for the supply to stabilize, and the pullup for the inputs can be enabled or disabled.

The two-level comparator can be configured for active-high and active-low logic. It monitors two dedicated digital inputs, and it supports additional features, such as reset sequencing and delayed reset. Both UV and OV thresholds are monitored individually and independently, providing flexibility when programming and monitoring application specific voltages.

The LTC2934IDC-2#TRPBF supervisor is based on Low Voltage Differential Signaling (LVDS) interface, making it highly suitable for high-speed, low-power applications. The on-board voltage supervisor supports up to 10V of input voltage range and provides a reset-pulse and open-drain output when one of the inputs exceeds the pre-programmed threshold. The reset pulse is transmitted after an adjustable reset delay of 0 ms up to 3.2sec.

The LTC2934IDC-2#TRPBF supervisor is mainly used in mobile, computing and communication devices, thanks to its high-speed, low-power operation and voltage-monitoring bottleneck. Its small form factor and adjustable logic levels (from 1.2V up to 13V in 100mV increments) make it an ideal choice for space-constrained devices. This device can also be used in industrial, automotive and medical applications for exact voltage-monitoring and protection.

In conclusion, the LTC2934IDC-2#TRPBF is an integrated supervisor device specifically designed to provide exact monitoring and protection in mobile, computing and communication applications. This easy-to-implement supervisor, with its wide range of features, is ideal for applications where precise monitoring and protection of system voltages is required. Thanks to its LVDS interface and adjustable logic levels, it can be easily integrated into a wide range of applications.
