TPL7407LEVM Performance Testing Using Lab Equipment
Output Parameter VOL Channel 1 Test Setup and Typical Results
This parameter was called collector emitter saturation voltage on the original TPL7407L device.
The data sheet has specifications for input voltages of 1.8V - 5V.
Board setup: Sweep output current on J2-1. Set desired input voltage on J1-1 [1.8V - 5V, and other
voltages]. Disconnect the relay supply on TB1-4. Measure output voltage on J2-1 (kelvin connections at
J2-1 and ground are highly recommended for accurate results).
