PCA2002
32 kHz watch circuit with programmable output period and pulse width
9. Limiting values
[1] When writing to the OTP cells, the supply voltage (V
DD
) can be raised to a maximum of 12 V for a time
period of 1 s.
[2] Connecting the battery with reversed polarity does not destroy the circuit, but in this condition a large
current flows which rapidly discharges the battery.
[3] Pass level; Human Body Model (HBM), according to Ref. 5 “
JESD22-A114”.
[4] Pass level; Machine Model (MM), according to Ref. 6 “
JESD22-A115”.
[5] Pass level; latch-up testing according to Ref. 7 “
JESD78” at maximum ambient temperature (T
amb(max)
).
[6] According to the NXP store and transport requirements (see Ref. 9 “
NX3-00092”) the devices have to be
stored at a temperature of +8 C to +45 C and a humidity of 25 % to 75 %. For long term storage products
deviant conditions are described in that document.
Table 9. Limiting values
In accordance with the Absolute Maximum Rating System (IEC 60134).
