3-Pin Voltage Supervisors

with Active-High, Push-Pull Reset

FEATURES

DESCRIPTION

The TLV810 family of supervisory circuits provides

circuit initialization and timing supervision, primarily

for DSPs and processor-based systems.

•

3-Pin SOT23 Package

Supply Current: 9 µA (Typical)

Precision Supply Voltage Monitor:

2.5 V, 3 V, 3.3 V, 5 V

Power-On Reset Generator with

Fixed Delay Time of 200 ms

Pin-for-Pin Compatible with MAX810

Temperature Range: –40°C to +125°C

Push-Pull, RESET Output

During power-on, RESET is asserted when the

supply voltage (V_DD) becomes higher than 1.1 V.

Thereafter, the supervisory circuit monitors V_DDand

keeps RESET active as long as V_DDremains below

the threshold voltage V_IT. An internal timer delays the

return of the output to the inactive state (low) to

•

ensure proper system reset. The delay time (t_d(typ)

200 ms) starts after V_DDhas risen above the

threshold voltage, V_IT. When the supply voltage drops

below the V_ITthreshold voltage, the output becomes

active (high) again. No external components are

required. All the devices in this family have a fixed

sense-threshold voltage (V_IT) set by an internal

voltage divider.

APPLICATIONS

•

DSPs, Microcontrollers, and Microprocessors

Wireless Communication Systems

Portable/Battery-Powered Equipment

Programmable Controls

Intelligent Instruments

Industrial Equipment

The product spectrum is designed for supply voltages

of 2.5 V, 3 V, 3.3 V, and 5 V. The circuits are

available in a 3-pin SOT-23 package. The TLV810

Notebook and Desktop Computers

Automotive Systems

devices are characterized for operation over

temperature range of –40°C to +125°C.
