Each part is laser trimmed to the desired threshold voltage which can be specified from 0.8V to 6.0V, in 0.V steps. The device includes a comparator, low-current highprecision reference, laser-trimmed divider, hysteresis circuit and output driver. The TC54 is available with either an opendrain or complementary output stage. In operation, the TC54's output (V OUT ) remains in the logic HIGH state as long as is greater than the specified threshold voltage (V DET). When falls below V DET, the output is driven to a logic LOW. V OUT remains LOW until rises above V DET by an amount V HYST, whereupon it resets to a logic HIGH.

Stresses above those listed under Absolute Maximum Ratings may cause permanent damage to the device. These are stress ratings only and functional operation of the device at these or any other conditions above those indicated in the operational sections of the specifications is not implied.

3 TIMING CHART DESCRIPTION OF OPERATION DETECT VOLTAGE V DET MINIMUM OPERATING VOLTAGE GROUND LEVEL OUTPUT VOLTAGE GROUND LEVEL V HYST + V DET RELEASE RESET OR VOLTAGE VOLTAGE Refer to the Timing Chart below. In normal steady-state operation, when > V DET, the output will be at a logic high. In the case of the TC54V, this is an open-drain condition. If and when the input falls below V DET, the output will pull down (Logic 0) to V SS. Generally, V OUT can pull down to within 0.5V of V SS at rated output current and input voltage. (See the Electrical Characteristics section). The output, V OUT, will stay valid until the input voltage falls below the Minimum Operating Voltage, (MIN), of 0.7V. Below this minimum operating voltage, the output is undefined. During power-up or anytime has fallen below (MIN), V OUT will remain undefined until rises above (MIN), at which time the output will become valid. V OUT will be in its active low state while (MIN) < < V DET +. (V DET + = V DET + V HYST). If and when the input rises above V DET +, the output will assume its inactive state. (High for TC54VC, open-drain for TC54VN). APPLICATIONS Refer to TelCom Semiconductor Application Note #2, Using the TC54 Voltage Detector.
