SGM809-LXN3L/TR
Brand: SG Micro
The SGM809-LXN3L/TR is a SG Micro 3-pin microprocessor supervisory circuit that monitors the system supply voltage and asserts a reset signal when VCC drops below the factory-programmed threshold (4.63 V for the L suffix). The reset output remains asserted for a minimum 140 ms after VCC recovers, ensuring stable processor restart. With 3 μA typical supply current and transient immunity to ignore fast VCC glitches, it provides low-power, reliable brown-out protection for microcontrollers, DSPs, and FPGA-based systems in a compact SOT-23-3 package.

Power Features & Applications
- Single-channel microprocessor supervisory circuit with 4.63 V factory-programmed threshold (±1.5%), asserting active-low RESET on brown-out and de-asserting after 140 ms minimum timeout
- Ultra-low 3 μA supply current with valid RESET output down to VCC = 1 V, ensuring reliable MCU/FPGA reset even during slow power ramp or deep brown-out conditions
- Excellent transient immunity rejects fast VCC glitches, preventing spurious resets from power-supply noise in industrial and automotive environments
- Ultra-compact SOT-23-3 package (2.9 × 1.3 mm, 0.95 mm pitch) — the smallest 3-pin supervisor footprint — ideal for space-constrained embedded designs
- Wide 1.0–5.5 V operating range with 8 factory threshold options (1.8 V, 2.5 V, 3.0 V, 3.3 V, 5 V nominal) for flexible system voltage monitoring
- Targets microcontroller and DSP brown-out protection, FPGA power-sequencing reset, industrial controller watchdog companion, and automotive ECU supply supervision
