TC54 Description
The TC54 Series are CMOS voltage detectors, suited especially for battery-powered applications because of their extremely low 1µA operating current and small surface-mount packaging. Each part is laser trimmed to the desired threshold voltage which can be specified from 1.1V to 6.0V and 7.7V, for a 2% and 1.5V to 6.0V for a 1% tolerance. The device includes a parator, low-current highprecision reference,...
TC54 Key Features
- Precise Detection Thresholds: Standard ±2.0%, Custom ±1.0%
- Small Packages: 3-Pin SOT-23A, 3-Pin SOT-89, 5-Pin SOT-23A (7.7V only)
- Low Current Drain: Typ. 1µA
- Wide Detection Range: 1.1V to 6.0V and 7.7V
- Wide Operating Voltage Range: 0.7V to 10V
TC54 Applications
- the output is driven to a logic LOW. VOUT remains LOW until VIN rises above VDET
- by an amount VHYST, whereupon it resets to a logic HIGH. Temp. Range -40°C to +85°C
