Notes

1. The circuit includes thermal protection. Operation above max. junction temperature may degrade device reliability.

2. A diode in series with the VBat input increases the permitted continuous voltage and pulse < 10 ms to -85 V.

A pulse ≤1µs is increased to the greater of |-70V| and |VBat -40V|.

3. RF1 and RF2 ≥ 20 Ω is also required. Pulse is supplied to TIP and RING outside RF1 and RF2.
