What this supervisor does
The 5962-8868503HA is an adjustable IC supervisor and power supply support device. It monitors a supply rail and asserts a reset or fault signal when the voltage drops below a programmed threshold, then releases it after the supply recovers. The 'adjustable' designation means the threshold is set by external resistors, giving flexibility across different rail voltages without changing the part number.
Lifecycle and sourcing reality
For BOM planning, this removes the urgency of a forced redesign or lifetime buy. RoHS non-compliant — the part contains lead (Pb) in the finish or internal construction. If your assembly line or end-product requires RoHS exemption (e.g., military, aerospace, or high-reliability applications where leaded solder is permitted), this is acceptable. For RoHS-mandated builds, a Pb-free alternative must be sourced.
Package and handling
— loose parts in a bag or tube, not tape-and-reel. This suits low-volume builds, prototypes, or repair stock where pick-and-place is not required. For automated assembly, verify that the package outline matches your feeder or request a tape-and-reel variant if one exists.
Functional alternative — TLV803EA29VDBZR
The TLV803EA29VDBZR is a simple reset/power-on reset IC with an active-low, open-drain output and a fixed 130 ms minimum reset timeout. It operates from 1.0 V supply and is rated -40°C to 125°C. The key difference: the 5962-8868503HA is adjustable (external resistors set the threshold), while the TLV803EA29VDBZR has a fixed threshold. They are not pin-compatible drop-in replacements — the 5962-8868503HA requires external resistor divider components that the TLV803 does not. If your design needs a fixed-threshold supervisor in a smaller surface-mount package, the TLV803 family is worth evaluating, but expect a board layout change.
