EM6353
Reset Circuit with Fixed Delay
Description
Features
The EM6353 is an ultra-low current reset circuit 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 after a
fixed reset timeout period. The threshold defines the
minimum allowed voltage which guarantees the good
functionality of the system. When VDD rises above VTH, the
output remains active for an additional delay time. This
allows the system to stabilize before getting fully active.
The EM6353 features three output types: active-low push-
pull, active-low open-drain and active-high push-pull.

200ms reset timeout period (25ms on request)
Ultra-low supply current of 2.9µA (VDD=3.3V)
Operating temperature range: -40°C to +125°C
±1.5% reset threshold accuracy
11 reset threshold voltages VTH: 4.63V, 4.4V, 3.08V,
2.93V, 2.63V, 2.2V, 1.8V, 1.66V, 1.57V, 1.38V, 1.31V

No external components
Small SC70-5L and SOT23-3L packages as well as ultra-low
supply current of 2.9µA make the EM6353 an ideal choice
for portable and battery-operated devices.
Immune to short negative VDD transients
Guaranteed Reset valid down to 0.8V
Threshold hysteresis: 2.1% of VTH

2)
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.
