CS2001
1.
2 A Switching
Regulator, and 5.
0 V, 100 mA Linear
Regulator with RESET
The CS2001 is a smart power supply ASIC utilized in automotive airbag systems.
It contains a current−mode switching
regulator with a 1.
2 A on−chip switch and a 5.
0 V, 100 mA linear
regulator.
The linear output capacitor must be 3.
3 μF or greater with an ESR in the range of 100 mΩ to 1.
0 Ω.
If the ESR of the cap is less than 100 mΩ, a series resistor must be used.
The switcher can be configured in either a boost or flyback topology.
The boost topology produces energy reserve the resistor divider connected to the VFB pin.
In the event of fault voltage VER which is externally adjustable (25 V maximum) through condi...
