TPS3840PH46規(guī)格書(shū)詳情

1 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):

– 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)

2 Applications

? Grid infrastructure: circuit breaker, smart meter,

other monitoring and protection equipment

? Factory automation: field transmitter, PLC.

? Building automation: fire safety, smoke detector,

and HVAC

? Electronic point of sale

? Portable, battery-powered systems

3 Description

Wide Vin allows monitoring 9V rails or batteries

without external components 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. Low Power-on-Reset (VPOR) prevents

false resets, premature enable or turn-on of next

device, and proper transistor control during power-up

and power-down.

Reset output signal is asserted when the voltage at

VDD drops below the negative voltage threshold (VIT-)

or when manual reset (MR) is pulled to a low logic

(VMR_L). Reset signal is cleared when VDD rise above

VIT- plus hysteresis (VIT+) and manual reset is floating

or above VMR_H and the reset time delay (tD) expires.

Reset time delay can be programmed by connecting

a capacitor between CT pin and ground. For a fast

reset CT pin can be left floating.

Additional features: Built-in glitch immunity protection

for MR and VDD, built-in hysteresis, low open-drain

output leakage current (ILKG(OD)).
