What this supervisor does and where it fits
Rated for -40°C to 125°C ambient, this part handles industrial enclosures, outdoor telecom cabinets, and under-hood automotive modules where a commercial-grade supervisor would drift or latch up. The SC-70-4 package (also known as SOT-343) is a compact footprint for space-constrained PCBs — think sensor nodes, motor-drive control boards, or BMS monitoring circuits.
Open-drain output — pull-up required
The open-drain output can pull the reset line low but cannot drive it high. An external pull-up resistor to the supervisor's supply rail is required.
Lifecycle and sourcing
It is RoHS non-compliant per the original release, so verify your assembly line's exemption status if you need lead-free solder.
