BUS driver/receiver IC
CA0013BM is a BUS driver/receiver IC for cars. The IC enables data communications by connecting an operation panel and components with bus cables.For logic input, the IC supports both 3.3V and 5V microcomputer outputs. The output is open collector, and can be connected to either 3.3V or 5V microcomputer input by adding pull-up resistor.BUS terminal is durable against failure by electric surge.
| Data signal input | Two-input OR logic（H: Driver ON, L: Driver off） |
|---|---|
| Data signal output | One-output (H: Voltage between BUS+ and BUS- ≧ 110m V,L: Voltage between BUS+ and BUS- ≦ 30m V) |
Built-in standby function ： Low consumption current in standby mode（Not over 1uA）
Built-in output protection circuit ： Operative when voltage between BUS+ and BUS- ≧9V.
Wide operating voltage range in the receiver mode: 0 to 4.5V.
Maximum number of bus connections ： 20
※ Maximum capacity between bus lines (BUS+ and BUS-): C=8000pF.
※ Be sure to insert a resistance of 60Ωbetween the bus lines before using.

LDO built-in High-side/Low-side Gate Driver IC
This is a 36V high-side/low-side gate driver capable of driving external Nch-FETs using the bootstrap method. A 36V bootstrap diode is built-in, and 3.3V and 5.0V can be used as input logic supply voltage. A thermal shutdown circuit and an under-voltage lockout circuit (UVLO) are included as protective function.
| High-side floating voltage | 36V |
|---|---|
| Output voltage range | 5V to 10V |
| Output current | ±1A MAX |
| Propagation delay | 40ns TYP |
LDO and bootstrap diodes that are built in to set the output voltage with external resistors significantly downsize the low-voltage power management system. Additionally, the status detection pins (DET) for thermal shutdown (TSD) and under-voltage lockout (UVLO) enables to build a control feedback system for microcontrollers.
