Power Management Integrated Circuit (PMIC) is an integrated circuit containing many components that can monitor, distribute and control electrical power. These devices help to reduce physical clutter, save energy and improve system design. One example of a PMIC is the LM3709XQBP-308/NOPB.

The LM3709XQBP-308/NOPB is a supervisor integrated circuit that helps to protect data lines and power supplies of electronic devices. It provides voltage monitoring and precise voltage control for systems using a wide range of voltages. The LM3709XQBP-308/NOPB is used in variety of appliances, including medical, telecommunications, consumer and automotive applications.

The LM3709XQBP-308/NOPB’s main feature is its ability to regulate and monitor voltage levels and all relevant signals. It provides single-channel monitoring and control from 0.8V to 6.2V, with accuracy to ±2%. It operates in a low power state when the circuit condition is within the desired voltage range and wakes up to detect out-of-range conditions such as overvoltage or undervoltage. The LM3709XQBP-308/NOPB also provides short-circuit protection and open drain output.

The LM3709XQBP-308/NOPB also has exceedingly low quiescent currents and can detect a wide range of input voltages. It also provides an adjustable switch threshold over the 0.8V to 6.2V device total operating range and the accuracy is ±2%. Additionally, when in low power mode, the device draws only 0.5µA.

The LM3709XQBP-308/NOPB provides adjustable dead bands, a low operating temperature range of -40C to 125C, and can hold up to 3.6V on its output. The adjustable dead-bands provide for noise immunity, ensuring the device does not act upon small, temporary voltage fluctuations. Additionally, the condition that triggers a fault is completely adjustable.

This PMIC is available in the 8-Pin NSOP surface mount package and is lead-free and RoHS compliant. The LM3709XQB-308/NOPB has a maximum operating frequency of 200kHz, a wide input range of -50V to 6.2V, and can measure a single DC voltage with a resolution of 3.2mV. Its maximum sampled current is 2.5mA, with a maximum low battery current of 8µA.

In summary, the LM3709XQBP-308/NOPB is a supervisor PMIC that helps reduce physical clutter, saves energy and improves system design. It provides voltage monitoring and precise voltage control, adjustable switch threshold, adjustable dead bands and other features. This PMIC is available in the 8-Pin NSOP surface mount package and is lead-free and RoHS compliant.
