The TS51111 includes several additional modules to allow simple
integration into wireless power systems. Integrated resistor dividers
with zero-current off-mode allow external ADC measurement of
PDC, PACKP, USB and thermistor voltages. High voltage switches are
included for communication modulation.
Power to an external controller is provided through an integrated
LDO. The ultra-low quiescent current regulator can supply high
output currents at low dropout with minimal current draw from the
battery.
Available in a 45 pin WCSP and 36 pin 6x6 QFN package.
