Table 12.
1. Valid for ambient operating temperature: T
2. For open drain pins IRQ/FT/OUT and SDA
3. STMicroelectronics recommends the RAYOVAC BR1225 or BR1632 (or equivalent) when a battery is used.
Table 13.
1. Externally supplied if using the SO8 package. STMicroelectronics recommends the KDS DT-38: 1TA/1TC252E127, Tuning
