GENERAL DESCRIPTION
The TEA1200TS is a fully integrated battery power unit
including a high-efficiency DC-to-DC converter which runs
from a 1-cell NiCd or NiMH battery and a low battery
detector. The circuit can be arranged in several ways to
optimize the application circuit of a power supply system.
Therefore, the DC-to-DC converter can be arranged for
upconversion or downconversion and the low battery
detector can be configured for several types of batteries.
Accurate low battery detection is possible while all other
blocks are switched off.
The DC-to-DC converter features efficient, compact and
dynamic power conversion using a digital control concept
comparable with Pulse Width Modulation (PWM) and
Pulse Frequency Modulation (PFM), integrated CMOS
power switches with a very low RDSon and fully
synchronous rectification.
The device operates at a switching frequency of 600 kHz
which enables the use of external components with
minimum size. The switching frequency can be
synchronized to an external high frequency clock signal.
Optionally, the device can be kept in PWM control mode
only. Deadlock is prevented by an on-chip undervoltage
lockout circuit.
Active current limiting enables efficient conversion in
pulsed-load systems such as Global System for Mobile
communication (GSM) and Digital Enhanced Cordless
Telecommunications (DECT).
The low battery detector has a built-in detection level
which is optimum for a 1-cell NiCd or NiMH battery.
