TPS3840DL29DBVR Product Details

Wide Vin allows monitoring 9V rails or batteries without external components and 24Vrails with external resistors. Nano-Iq extends battery life for low power applications andminimizes current consumption when using external resistors. Fast start-up delay allows thedetection of a voltage fault before the rest of the system powers up providing maximum safety inhazardous start-up fault conditions. Low Power-on-Reset (VPOR) preventsfalse resets, premature enable or turn-on of next device, and proper transistor control duringpower-up and power-down.

Reset output signal is asserted when the voltage at VDD dropsbelow the negative voltage threshold (VIT-) or when manual reset(MR) is pulled to a low logic(VMR_L). Reset signal is cleared whenVDD rise above VIT- plus hysteresis(VIT+) and manual reset is floating or aboveVMR_H and the reset time delay(tD) expires. Reset time delay can be programmed by connecting a capacitorbetween CT pin and ground. For a fast reset CT pin can be left floating.

Additional features: Built-in glitch immunity protection for MRand VDD, built-in hysteresis, low open-drain output leakage current(ILKG(OD)).



  • 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):
      • 50 μs (no capacitor) to 6.2 s (10-μF)
    • Active-low manual reset (MR)
    • 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)
