The LTC1232CS8#TRPBF is a 5V microprocessor supervisor IC from LT designed to monitor power supply voltage and assert reset outputs during power-up, power-down, and brownout conditions. The reset threshold is selectable via the TOL pin: when connected to GND, reset activates when V CC falls below 4.75V (typical 4.62V); when connected to V CC, threshold is 4.5V (typical 4.37V). The time-out delay is configurable through the TD pin: 150ms (TD = GND), 600ms (TD floating), or 1.2s (TD = V CC).
The device includes a push-button reset input (PB RST) that is debounced for a minimum of 40ms, and the reset outputs remain active for a minimum of 250ms after PB RST is released. Additionally, the ST input forces the reset outputs active when driven high or low longer than the selected time-out period. A 0.1µF bypass capacitor is required on the V CC pin.
The IC is housed in an 8-SOIC surface mount package, suitable for compact PCB designs.
The nominal supply voltage is 5V. The reset trip point is selectable: 4.75V (with TOL=GND) or 4.5V (with TOL=VCC).
It is available in an 8-SOIC surface mount package.
The time-out delay is selectable: 150ms (TD=GND), 600ms (TD floating), or 1.2s (TD=VCC).
The push-button reset input has a minimum debounce time of 40ms.
The reset outputs remain active for a minimum of 250ms after PB RST is released or after ST is driven high/low longer than the timeout period.
