Two-rail supervisor in a SOT-23-6
One channel is fixed at 4.63V; the second is adjustable via an external resistor divider, giving flexibility for a secondary rail like 3.3V, 2.5V, or 1.8V. The reset output stays low for a minimum of 140ms after both rails recover, meeting the power-on reset timing for most MCUs, DSPs, and FPGAs. Housed in a 6-pin SOT-23 package, it suits space-constrained boards in industrial control, automotive body electronics, and base-station line cards where two voltages need sequencing or supervision.
140ms reset timeout — what it buys the system
If your MCU boots from a high-speed external crystal or a flash controller with a wake-up delay, this window prevents spurious fetch from uninitialized registers. For designs using a separate watchdog supervisor, the timeout must be shorter than the watchdog's service window to avoid false resets on power-up.
The open-drain output allows wired-OR connection with other reset sources.
