TLV803E, TLV809E, TLV810E Low Power 250-nA I_Qand Small Size Supply Voltage

Supervisors

1 Features

3 Description

•

Ensured RESET/RESET for VDD = 0.7 V to 6 V

Fixed time delay: 40 µs, 10 ms, 50 ms, 100 ms,

200 ms, 400 ms

Supply current (IDD): 250 nA (typical)

– 1 µA (maximum for VDD = 3.3 V)

Output topology:

The TLV803E, TLV809E, and TLV810E are enhanced

alternatives to the TLV803, TLV853, TLV809, LM809,

TPS3809 and TLV810. TLV80xE and TLV81xE offer

low quiescent current I _Q, higher accuracy, wider

•

temperature range, and lower power-on-reset (V_POR

)

for increased system reliability.

The TLV80xE and TLV81xE family are low I_Q(250 nA

typical, 1 µA max), voltage supervisory circuits (reset

IC) that monitor VDD voltage level. These devices

initiate a reset signal whenever supply voltage VDD

drops below the factory programmed falling threshold

voltage, V_IT–. The reset output remains low for a fixed

reset time delay t_Dafter the VDD voltage rises above

the rising voltage threshold (V_IT+) which is equivalent

to the falling threshold voltage (V_IT-) plus hysteresis

(V_HYS).

– TLV809E: push-pull, active-low

– TLV803E: open-drain, active-low

– TLV810E: push-pull, active-high

Under voltage detection:

– High accuracy: ±0.5% (typical)

– (V_IT–): 1.7 V, 1.8 V, 1.9 V, 2.25V, 2.4 V, 2.64 V,

2.93 V, 3.08ꢀV, 3.3V, 4.2V, 4.38 V, 4.55V, 4.63 V

Package:

– SOT23-3 (DBZ) (with pin 1 = GND)

– SOT23-3 (DBZ) (with pin 1 = RESET/RESET)

– SOT23-3 (DBZ) (with pin 3 = GND)

– SC-70 (DCK)

•

These devices have integrated glitch immunity to

ignore fast transients on the VDD pin. The low I_Qand

high accuracy (±0.5% typical) makes these voltage

supervisors ideal for use in low-power and portable

applications. The TLV80xE and TLV81xE devices are

specified to have the defined output logic state for

supply voltages down to V_POR= 0.7 V. The TLV80xE

and TLV81xE devices are available in industry

standard 3-pin SOT23 (DBZ) and SC70 (DCK)

packages and very compact X2SON (DPW) package.

– X2SON-5 (DPW)

•

Temperature range: ꢀ–40°C to +125°C

Pin-to-pin compatible with MAX803/809/810,

APX803/809/810
