Multiple rails, sequencing, supervision, and protection in one integrated chip.
Power Switch / Load Switch (PSW)
Integrated MOSFET switches with controlled turn-on, soft-start, and protection.
Voltage Reference
Stable, low-noise voltage source for ADCs, DACs, and precision analog circuits.
MOSFETs, BJTs, Zeners, Schottkys, switching diodes, rectifiers, and bridges: the workhorse silicon behind every analog and power design.
