Overview
Wide operating voltage range: 1.5V to 10V Nano-power supply current: 300nA (typical), 700nA (maximum) Fixed threshold voltage (VIT-) threshold range: 1.6V to 4.9V (in 0.1V steps) High accuracy: 1% (typical), 1.5% (maximum) Built-in hysteresis (VIT+): 1.6V < VIT ≤ 3.0V = 100mV (typical), 3.1V ≤ VIT < 4.9V = 200mV (typical) Fast startup delay (tSTR T): 220μs (typical), 350μs (maximum) Programmable reset delay time (tD): 50μs (no capacitor) to 6.2s (10μF) Active-low manual reset (MR(overline)) Three output topologies: - TPS3840DL: open-drain, active-low (RESET), requires pull-up resistor - TPS3840PL: push-pull, active-low (RESET) - TPS3840PH: push-pull, active-high (RESET) Wide temperature range: -40°C to +125°C Package: SOT23-5 (DBV)
Applications
- Grid infrastructure: circuit breakers, smart meters, and other monitoring and protection equipment
- Factory automation: field transmitters, PLC
- Building automation: fire safety, smoke detectors, and HVAC
- Electronic point-of-sale
- Portable battery-powered systems
Key features
- Wide operating voltage range: 1.5V to 10V
- Nano-power supply current: 300nA (typical), 700nA (maximum)
- Fixed threshold voltage (VΠ-) threshold range: 1.6V to 4.9V (in 0.1V steps), high accuracy: 1% (typical), 1.5% (maximum)
- Built-in hysteresis (VIT+): 1.6V < VIT ≤ 3.0V = 100mV (typical), 3.1V ≤ VIT < 4.9V = 200mV (typical)
- Fast startup delay (tSTR T): 220μs (typical), 350μs (maximum)
- Programmable reset delay time (tD): 50μs (no capacitor) to 6.2s (10μF)
- Active-low manual reset (MR(overline))
- Three output topologies: TPS3840DL open-drain, active-low (RESET), requires pull-up resistor; TPS3840PL push-pull, active-low (RESET); TPS3840PH push-pull, active-high (RESET)
- Wide temperature range: -40°C to +125°C
- Package: SOT23-5 (DBV)
- Built-in glitch suppression protection and built-in hysteresis for MR(overline) and VDD
- Low open-drain output leakage current (ILKG(OD))
