Description
Description
The STM1066 device monitors VCC, and connects OUT to VIN or GND, based on the VCC
level (above VTH+ or below VTH- ) and the state of EN and INH inputs.
The device offers several voltage thresholds, VTH+ (see Table 8) and it is available in
miniature flip chip 6-bump package.

Operation

STM1066
Operation
The STM1066 connects or disconnects the output OUT, from the VIN pin based on the
logical combination of the enable input (EN), the inhibit input (INH), and the supply voltage
level, VCC (see Table 2 or Figure 11 for more details).
2.1
Output, OUT
If the enable input is in a logic high state and inhibit input is in a logic low state, the output
will be connected to VIN input as VCC rises above the VTH+ voltage threshold. Otherwise, the
output is connected to ground GND. The output is current limited (see Table 5).
2.2
Enable input, EN
A Logic low on the enable input disconnects the output from VIN and disables the device,
which enters a standby mode with very low current consumption (see Table 5).
2.3
Inhibit input, INH
A logic high on the inhibit input disconnects the output from VIN.

Maximum ratings
Stressing the device above the rating listed in the “Absolute maximum ratings” table may
cause permanent damage to the device. These are stress ratings only and operation of the
device at these or any other conditions above those indicated in the Operating sections of
this specification is not implied. Exposure to absolute maximum rating conditions for
extended periods may affect device reliability. Refer also to the STMicroelectronics SURE
Program and other relevant quality documents.

1. Valid for ambient operating temperature: TA = –30°C to +85°C; VCC = 2.7 V to 5.5 V (except where noted).
2. Guaranteed by design.
3. For VCC below VTH-, the output remains low down to VCC = 1 V. Below VCC = 1 V the voltage VIN must be less than
VOUT-OL (max.) to guarantee output low voltage less than 0.3 V.
