1 Features

3 Description

The TLV803E, TLV809E, and TLV810E are

enhanced alternatives to the TLV803, TLV853,

TLV809, LM809, TPS3809 and TLV810. TLV803E,

TLV809E and TLV810E offer lower supply current for

battery-powered applications, higher accuracy, wider

•

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)

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

for increased system reliability.

)

–

1 µA (maximum for VDD = 3.3 V)

•

Output topology:

The TLV803E, TLV809E, and TLV810E 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)

Nominal voltage monitor: 3 V, 3.3 V, 5 V

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

2.93 V, 3.08 V, 4.38 V, 4.63 V

•

Package:

These devices have integrated glitch immunity to

ignore fast transients on the VDD pin. The low current

consumption and 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

available in industry standard 3-pin SOT23 (DBZ)

package, 3-pin SC70 (DCK) package, and very

compact X2SON (DPW) package.

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