The PS501 combines a high-performance, low-power
Microchip PIC18 microcontroller core together with
PowerSmart proprietary monitoring/control algorithms
and 3D cell models stored in 16 Kbytes of on-chip
reprogrammable Flash memory.
Analog resources include a 16-bit sigma-delta integrating
A/D and mixed signal circuitry for precision
measurement of battery current, temperature and voltage
and for direct connection to 4-cell series Lithium
Ion packs. On-chip EEPROM is provided for storage of
user customizable and “learned” battery parameters.
An industry standard 2-wire SMBus interface supports
host communication using standard SBData
commands and status.
Additional integrated features include a high accuracy
on-chip oscillator and temperature sensor. Twelve general
purpose pins support charge or safety control or
user programmable digital I/O. Eight of them can be
used as LED drivers and two are open drain for direct
FET drive.
The PS501 can be configured to accommodate all
Lithium rechargeable battery chemistries, including
Li Ion graphite, Li Ion hard carbon and Li Ion polymer,
with direct connection to 2 to 4 series cell configurations.
