ZXCT1012
Reduced height micro-power current monitor
Description
The ZXCT1012 is a high side current sense
monitor. Using this type of device eliminates
the need to disrupt the ground plane when
sensing a load current.
The ZXCT1012 takes the voltage developed
across a small value resistor and translates it
into a proportional output current. A user
defined output resistor scales the output
current into a ground referenced voltage.
The ZXCT1012 has the accuracy specification of
the ZXCT1010 but in TSOT23-5, and TDFN3x3-5.
Features
• 2.5V to 20V supply range
• 3.5µA quiescent current
• Current output - user set gain
• Thin package - TSOT23-5 and TDFN3x3-5
• Temperature range -40 to 85°C
Pin connections
A minimum operating current of just 3.5µA,
combined with its TSOT23-5 package make it
suitable for portable battery equipment where
size and current consumption are critical.
The wide input voltage range down to as low as
2.5V make it suitable for a wide range of
applications requiring direct operation from a
battery.
Applications
• Battery fuel gauge
• Battery chargers
• Overcurrent monitor
• Power management
