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.
