DESCRIPTION
TSM108 is a P-channel MOSFET controller which
ensures constant voltage and constant current in
Switching Mode Power Supply (step down) like in
automotive battery charging applications.
TSM108 can easily be configured for very wide
voltage and current needs.
TSM108 is built in rugged BCD technology and
includes a PWM generator, Voltage and Current
control loops, a precision Voltage Reference, and
a P-Mosfet Gate Drive output. TSM108 can
sustain 60V on Vcc, and therefore meet the
standard Load Dump requirements in the
Automotive field.
TSM108 includes security functions which lock the
PMosfet in OFF state: OVLO (Over Voltage
Lockout) and UVLO (Under Voltage Lockout). The
P-Mosfet Gate is also protected from over voltage
drive thanks to a 12V clamping protection circuit.
TSM108 includes a standby feature which allows
very low quiescent current when activated, as well
as safe P-Mosfet Off state.
TSM108 is suitable for car environment
accessories, as well as numerous other DC/DC
step down regulation.
