Manual for Vishay's SiP32419EVB and SiP32429EVB load switch evaluation boards, covering schematics, component details, and test procedures.
This manual provides detailed information on the SiP32419EVB and SiP32429EVB evaluation boards, including power terminals, capacitor specifications, enable and fault flag connections, and over-current protection settings. It includes schematics, a bill of materials, and test results for lab experiments. The boards are designed to evaluate load switch features such as programmable soft power-up and over-current protection.
The evaluation board supports input voltages from 6 V to 24 V, with components like 10 μF capacitors rated at 50 V. The enable terminal operates with a 1.5 V threshold, and fault/power good flags are open-drain outputs requiring external bias. Current limits are set using an external resistor, and soft power-up time is programmable via capacitors and resistors.
| Switch Resistance | 56 mΩ |
|---|---|
| Enable Threshold Voltage | 1.5 V |
| Disable Threshold Voltage | 0.4 V or lower |
| Capacitor Value | 10 μF |
| Capacitor Voltage Rating | 50 V |
| Package Type | DFN10 3 mm x 3 mm |
The enable threshold voltage is 1.5 V.
For SiP32419EVB, the switch remains off and the fault flag remains on. For SiP32429EVB, the fault flag releases 150 ms after the fault is cleared, and the switch turns on at the programmed slew rate.
