TPS3840 Description
Wide Vin allows monitoring 9V rails or batteries without external ponents and 24V rails with external resistors. Nano-Iq extends battery life for low power applications and minimizes current consumption when using external resistors. Fast start-up delay allows the detection of a voltage fault before the rest of the system powers up providing maximum safety in hazardous start-up fault conditions.
TPS3840 Key Features
- 1 Wide operating voltage: 1.5 V to 10 V
- Nano supply current: 300 nA (Typ), 700 nA (Max)
- Fixed threshold voltage (VIT-)
- Threshold from 1.6 V to 4.9 V in 0.1-V steps
- High accuracy: 1% (Typ), 1.5% (Max)
- Built-in hysteresis (VIT+)
- 1.6 V < VIT- ≤ 3.0 V = 100 mV (Typical)
- 3.1 V ≤ VIT- < 4.9 V = 200 mV (Typical)
- Start-up delay (tSTRT): 220 µs (Typ), 350 µs (Max)
- Programmable reset time delay (tD)
TPS3840 Applications
- Grid infrastructure: circuit breaker, smart meter, other monitoring and protection equipment
