SBVS085H –JANUARY 2007–REVISED JUNE 2012

LOW-QUIESCENT-CURRENT PROGRAMMABLE-DELAY SUPERVISORY CIRCUIT

Check for Samples: TPS3808-Q1

FEATURES

DESCRIPTION

•

Qualified for Automotive Applications

The TPS3808 microprocessor supervisory circuits

monitor system voltages from 0.4 V to 5 V, asserting

an open-drain RESET signal when the SENSE

voltage drops below a preset threshold or when the

manual reset (MR) pin drops to a logic low. The

RESET output remains low for the user-adjustable

delay time after the SENSE voltage and MR return

above their thresholds.

Power-On Reset Generator With Adjustable

Delay Time: 1.25 ms to 10 s

•

Very Low Quiescent Current: 2.4 μA Typ

High Threshold Accuracy: 0.5% Typ

Fixed Threshold Voltages for Standard Voltage

Rails From 1.2 V to 5 V and Adjustable Voltage

Down to 0.4 V Are Available

The TPS3808 uses a precision reference to achieve

0.5% threshold accuracy for V_IT≤ 3.3 V. The reset

delay time can be set to 20 ms by disconnecting the

C_Tpin, 300 ms by connecting the C_Tpin to V_DDusing

a resistor, or can be user adjusted between 1.25 ms

and 10 s by connecting the C_Tpin to an external

capacitor. The TPS3808 has a very low typical

quiescent current of 2.4 μA, so it is well suited to

battery-powered applications. It is available in a small

SOT-23 package and is fully specified over a

temperature range of –40°C to 125°C (T_J).
