Description:Precision monitoring of +5.0 V (±5%, ±10%, ±20%), +3.3 V (±5%, ±10%), +3.0 V (±10%) and +2.5 V (±5%) power supplies; Offered in two output configurations: - CAT811: Active LOW reset - CAT812: Active HIGH reset; Manual reset input; Direct replacements for the MAX811 and MAX812 in applications operating over the industrial temperature range; Reset valid down to VCC = 1.0 V; 6 µA power supply current; Power supply transient immunity; Industrial temperature range: -40°C to +85°C; Compact 4-pin SOT143 package
A good PCB layout for the CAT811LTBI-GT3 involves keeping the input and output traces separate, using a solid ground plane, and placing decoupling capacitors close to the device. Additionally, it's recommended to use a 4-layer PCB with a dedicated power plane and a dedicated ground plane.
The CAT811LTBI-GT3 requires a single 3.3V power supply. It's recommended to use a low-dropout linear regulator (LDO) to power the device. Power sequencing is not critical, but it's recommended to power up the device after the power supply has stabilized.
The CAT811LTBI-GT3 has an operating temperature range of -40°C to 125°C. The device's performance may degrade at higher temperatures, with a maximum junction temperature of 150°C. It's recommended to keep the device within the specified operating temperature range for optimal performance.
During power-up, the CAT811LTBI-GT3's output is undefined until the device is fully powered up. It's recommended to add a reset circuit or a power-on reset (POR) circuit to ensure the output is in a known state during power-up. During power-down, the output will be in a high-impedance state.
The CAT811LTBI-GT3 has built-in ESD protection diodes on all pins. However, it's still recommended to follow proper ESD handling procedures when handling the device. Latch-up prevention measures include using a latch-up immune process and following proper design guidelines to prevent latch-up conditions.
