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 VDD stays above the threshold voltage,
the output stays inactive. If VDD drops below VTH, the output
goes active. The output is guaranteed to be in the correct
state for VDD down 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.

Immune to short negative VDD transients
Guaranteed Reset valid down to 0.8V
Threshold hysteresis: 2.1% of VTH
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.

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.

Note 1: Production tested at +25°C only. Over temperature limits are guaranteed by design, not production tested.
VDD min=0.9V for active-high versions (EM6352Z).
Note 2: RESET (RESET) open.
Note 3: Threshold voltage is specified for VDD falling.
Note 4: Typical variation ∆VTH of VTH at a given temperature TA is calculated as follows:
∆VTH
∆TA
∆VTH(T = TA ) =
× VTH × TA − 25°C
Example:
for version VTH=2.93V, variation at TA=70°C is equal to ∆VTH(70°C)=±50
10-6 x 2.93 x (70-25)=±6.59mV

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.
