The BTS70020-1ESP is a Smart High-Side Power Switch, providing protection functions
and diagnosis. The product has a Capacitive Load Switching mode implemented to charge
capacitive loads and to reduce current peaks during switch on of capacitors.

Protection Features:
• Absolute and dynamic temperature limitation with controlled reactivation
• Overcurrent protection (tripping) with Intelligent Latch
• Under voltage shutdown
• Overvoltage protection with external components

Thermal Model description:
THERMAL_MODEL=1: P=1W; T=85°C; PCB type: 1s0p 300mm2
THERMAL_MODEL=2: P=1W; T=85°C; PCB type: 1s0p 600mm2
THERMAL_MODEL=3: P=1W; T=85°C; PCB type: footprint
THERMAL_MODEL=4: P=1W; T=85°C; PCB type: 2s2p
where: P=power injected in chip; T=ambient temperature

The ambient temperature of the entire chip can be set by connecting a voltage source to TAMB
pin. Junction temperature can be monitored on TJ output pin. TJ is always TAMB + temperature
due to self-heating of the DMOS.
