The ACST310-8B is part of STMicroelectronics’ ACST (Advanced Composite Screening Technology) Voltage Supervisor product range. It is a low-power voltage supervisor designed to detect power supply errors, down-lines, and/or improper power supply. It provides an integrated reset signal that can be used to alert when a voltage level is out of range. It is available in an 8-pin SOIC package with extended temperature range of -40°C to +125°C. The ACST310-8B features Under-Voltage Lockout (UVLO) protection, a 4.4V – 5.6V voltage monitoring tolerance range, and an active high indicator output pin. In addition, the device offers a manual reset input, an internally pulled-up manual reset pin, and an active-low open-drain reset output pin.
