EM6352

Voltage Detector, High-Precision

Description

Features

The EM6352 is an ultra-low current voltage detector

available in a large variety of configurations and very small

packages for maximum flexibility in all end-applications up to

125°C and using power supplies between 1.5V and 5.5V.

This circuit monitors the supply voltage of any electronic

system, and generates the appropriate reset signal without a

delay time. The threshold defines the minimum allowed

voltage which guarantees the good functionality of the

system. As long as V_DDstays above the threshold voltage,

the output stays inactive. If V_DDdrops below V_TH, the output

goes active. The output is guaranteed to be in the correct

state for V_DDdown to 0.8V. There are 12 reset threshold

voltages starting as low as 1.31V and up to 4.63V. The

EM6352 features three output types: active-low push-pull,

active-low open-drain and active-high push-pull.

Ultra-low supply current of 2.7µA (V_DD=3.3V)

Operating temperature range: -40°C to +125°C

±1.5% reset threshold accuracy

12 reset threshold voltages V_TH: 4.63V, 4.4V, 3.08V,

2.93V, 2.63V, 2.26V, 2.2V, 1.8V, 1.66V, 1.57V, 1.38V,

1.31V

3 reset output options:

Active-low RESET push-pull

Active-low RESET open-drain

Active-high RESET push-pull

No external components

Immune to short negative V_DDtransients

Guaranteed Reset valid down to 0.8V

Threshold hysteresis: 2.1% of V_TH

Small SC70 and SOT23 packages as well as ultra-low

supply current of 2.7µA make the EM6352 an ideal choice

for portable and battery-operated devices.

Very small SOT23-5L, SOT23-3L, SC70-3L and

SC70-4L (SC-82AB) packages

Top marking with 4 characters is standard from 2003. For lead-free/green mold (RoHS) parts, the first letter of top

marking with 4 characters begins with letter “B” instead of letter “A”. Bottom marking indicates the lot number.

This device has built-in protection against high static

voltages or electric fields; however, anti-static precautions

must be taken as for any other CMOS component. Unless

otherwise specified, proper operation can only occur when

all terminal voltages are kept within the voltage range.

Unused inputs must always be tied to a defined logic

voltage level.

Traceability for small packages

Due to the limited space on the package surface, the bottom marking contains a limited number of characters that provide only partial

information for lot traceability. Full information for complete traceability is however provided on the packing labels of the product at

delivery from EM. It is highly recommended that the customer insures full lot traceability of EM product in his final product.
