The LP3470M5-3.08/NOPB from Texas Instruments is a highly reliable, microprocessor supervisory circuit designed to monitor the power supplies in digital systems. This device provides maximum flexibility for power supply monitoring and reset control, particularly in systems with multiple power supplies.

• Reset Assertion: Asserts a reset if any monitored supplies fall below its threshold or if the manual reset input is asserted.
• Reset Delay: The reset output remains asserted for a period after all supplies rise above their thresholds and the manual reset input is de-asserted. The reset delay can be set by an external capacitor.
• Supply Voltage Monitoring: Can monitor four system supply voltages without an external resistor divider network, reducing system power consumption and making it ideal for portable battery-operated equipment. Capable of monitoring a 1.8V to 5V supply without external components.
• Package: Small 5-pin SOT-23 package.
• Temperature Range: Operates over a wide temperature range of -40°C to 85°C.
• Manual Reset Input: Can generate a reset pulse of at least 1ms by a push button or microprocessor.
• Reset Output: Active low and guaranteed to be in the correct state for VCC greater than 1V.
• Supply Current: Low supply current of 15µA (typical).
• Precision Supply Voltage Monitor: Precision supply voltage monitor of 3.08V.
• Power Supply Transient Immunity: Can withstand fast transients on the VCC line without generating a false reset pulse.
• Compliance: RoHS compliant and lead-free (NOPB), environmentally friendly.

In conclusion, the LP3470M5-3.08/NOPB is a reliable, efficient, and versatile microprocessor supervisory circuit that provides maximum flexibility for power supply monitoring and reset control.
