MAX6306UK44D3+T is a low-cost and ultra-small voltage supervisor integrated circuit (IC) designed to monitor single power supplies reliably and accurately within a given voltage range. This PMIC can be used in a wide range of applications and devices such as microprocessors, computer and telecommunications systems, lighting systems, and automotive systems. It is also commonly used for buck converters, resonant converters, and linear regulators.

MAX6306UK44D3+T supervisors offer reliable protection from voltage glitches and heavey load current transients. It utilizes an advanced low-power CMOS technology to sense the supply voltage and assert a reset signal when the supply voltage drops below a predetermined value. The reset signal is released when the supply voltage rises above a second predictable level. It can also detect rising or falling voltage depending on the programming.

MAX6306UK44D3+T comes with a wide operating voltage range of 1.14V to 6.5V and a wide temperature range of -40°C to +125°C. The IC features an active-low reset output with a delay of 2.65 to 4.3ms. The reset delay is dependent on supply voltage and reset threshold voltage programming. The reset threshold voltage range can be set from 1.2V to 5.8V, making it ideal for microprocessor applications or for advanced battery backup systems. In addition, the reset output includes an open-drain output with up to 10mA source current capability. It also has an active-low fault output, with a delay of 2.1ms to 4.3ms, and an active-high reset output with output delay as low as 650ns.

As a voltage supervisor IC, the MAX6306UK44D3+T operates in two modes: monitoring and resetting. On normal power up operations, the supervisor monitors the supply voltage and will output the reset signal if detected activity falls outside of the pre-programmed voltage range. On power down, the supervisor will toggle the output signal to set the device into reset. The supervisor also actively monitors variations in the voltage rail for changes such as a significant drop in voltage or rising of voltage. The supervisor will then take corrective action to reset the system.

The MAX6306UK44D3+T supervisor IC is a highly reliable and versatile solution for power supply monitoring, voltages glitches, and high current transient protection for a wide range of applications and devices. It provides superior performance with a wide operating voltage range, low power consumption, and low reset threshold voltage ranges. This solution is suitable for device reset in robust applications as well as providing integrated fault outputs along with reset outputs. It is also available in a 8-pin, ultra-small TDFN package making it space-saving and cost-effective.
