It is designed for systems that need reliable power-up sequencing and brown-out detection across multiple supply domains — think FPGA core, I/O, and auxiliary rails in a single compact SOT-23-8 package. The three threshold voltages are 0.788 V, 1.575 V, and an adjustable input, letting you supervise a mix of fixed low-voltage rails and a custom threshold set by an external resistor divider. The push-pull output drives logic inputs directly without a pull-up resistor. Reset timeout is a minimum of 140 ms, giving the downstream ICs time to stabilise after the monitored rails come into regulation. The operating temperature range of -40°C to 85°C covers industrial environments — outdoor telecom cabinets, factory-floor controllers, and automotive cabin-zone electronics. ## Package and mounting SOT-23-8 is a standard surface-mount package. It suits dense PCB layouts where board area is at a premium. The supplier device package is also SOT-23-8, so no footprint mismatch between the generic case code and the manufacturer's recommended land pattern. ## Lifecycle and compliance The ROHS3 rating covers the full substance restriction, including the four phthalates — no exemption expiry to track.","metaTitle":"MAX6729KAVDD3+ Power Supply Monitor, SOT-23-8, 3-Channel","metaDescription":"MAX6729KAVDD3+ power supply monitor from Analog Devices.
