TC54
Voltage Detector
Features:
• ±2.0% Detection Thresholds
• Small Packages: 3-Pin SOT-23A, SOT-89, and
TO-92
• Low Current Drain: 1 µA, typical
• Wide Detection Range: 1.1V to 6.0V
• Wide Operating Voltage Range: 0.7V to 10V
General Description:
The TC54 series are CMOS voltage detectors espe-
cially well-suited for battery-powered applications
because of their extremely low 1 µA operating current
and small surface-mount packaging. Each part is laser-
trimmed to the desired threshold voltage, which can be
specified from 1.4V to 6.0V with a 2% tolerance.
The TC54 is available with either an open-drain or com-
plementary output stage. During operation, the output
(V
OUT
) remains in the logic-high state as long as V
IN
is
greater than the specified threshold voltage (V
DET
–).
When V
IN
falls below V
DET
–, the output is driven to a
logic-low. V
OUT
remains low until V
IN
rises above
V
DET
– by an amount V
HYST
, when it resets to a logic-
high state.
Applications:
Battery Voltage Monitoring
Microprocessor Reset
System Brown-Out Protection
Switching Circuit in Battery Backup
Level Discriminator
