Datasheet
Voltage Detector IC Series
Bipolar
Voltage Detector ICs
BD47xx series
●General
Description
The BD47xx series is a Voltage Detector IC,
developed to prevent system errors at transient state,
when the power of CPU or logic circuit switches
ON/OFF or in cases of momentary shut down. These
ICs consist of three terminals (power supply, GND and
reset output) to detect power supply voltages and
outputs reset signals of various systems. These ICs
are ultra-compact and have low current consumption,
making them ideal for portable products.
●Key
Specifications
Detection voltage range:
1.9V to 4.6V (Typ.)
0.1V steps
High accuracy detection voltage:
±1%
Low current consumption:
1.6µA (Typ.)
Operating temperature range:
-40°C to +75°C
●Package
SSOP5
2.90mm x 2.80mm x 1.25mm
●Features
High accuracy detection
Low current consumption
Very small package
Open collector “L” reset output
Package SSOP5 is similar to SOT-23-5 (JEDEC)
●Applications
Circuits using microcontrollers or logic circuits that require
a reset.

Please help me check my 2812AD
Why is the conversion accuracy of my 2812 so poor? It should be 4095 at 3V, but my chip converts to 3953, and only 3652 at 2.75V, which is almost 100 different from the ideal value.Is the conversion a...
