Electrical Specifications
Recommended operating conditions unless otherwise noted. Refer to “Block Diagram” on page 3 and “Typical
Application Schematic” on page 4. V IN = 5.6V to 24V, or VCC_5V = 5V ±10%, T A = -40°C to +85°C (Note 7),
Typical values are at T A = +25°C. Parameters with MIN and/or MAX limits are 100% tested at +25°C, unless
otherwise specified. Temperature limits established by characterization and are not production tested.
