ZSM561G Zetex Semiconductors, ZSM561G Datasheet - Page 4

• Manufacturer Part Number: ZSM561G
• Description: SUPPLY VOLTAGE MONITOR
• Manufacturer: Zetex Semiconductors

Note:
1. Maximum package power dissipation must be observed.
2. Maximum power dissipation for the SOT223 and SO8 packages is calculated assuming that
the device is mounted on a PCB measuring 2 inches square.
3. Low duty cycle pulse techniques are used during test to maintain junction temperatures as
close to ambient as possible
4. A time delayed reset can be accomplished with the additional Cd.
5. Operation above V
