The power transistor is built by a N-channel vertical power MOSFET with charge pump. The design is based on Smart power chip on chip technology. The BTS50080-1EGA has ground referenced CMOS compatible inputs. ReverSaveTM is a protection feature that causes the power transistor to switch on in case of reverse polarity. As a result, the power dissipation is reduced. Infineon INTELLIGENT LATCH ensures a latched switch-off and reporting in case of fault condition. The Infineon ENHANCED SENSE pin IS provides a sophisticated diagnostic feedback signal including current sense functionality, open load in ON-state (via sense signal) and open load and short to battery in OFF-state. Diagnostic reporting can be enabled and disabled by the DEN-Pin in ON-state and OFF-state. In OFF-state, open load detection can also be disabled by the DEN-Pin to optimize stand-by current.

Datasheet 17 V1.0, 2009-04-06 Smart High-Side Power Switch BTS50080-1EGA Protection Functions 6 Protection Functions The BTS50080-1EGA provides embedded protective functions. Integrated protection functions are designed to prevent IC destruction under fault conditions described in the data sheet. Fault conditions are considered as “outside” normal operating range. Protection functions are neither designed for continuous nor repetitive operation. 6.1 Short Circuit Protection The internal logic permanently monitors the load current IL. In the event the load current exceeds the short circuit shutdown threshold (IL>IL(SC)), the device will switch off immediately. Any protective switch off latches the output. Please refer to Figure 14 for details. The protective switch off remains latched until the fault is acknowledged and reset by a falling edge at the DEN pin. See also Chapter 6.4. VIN t VDEN IL t I L(SC) reset latch Figure 14 reset latch latch reset latch reset t latch I_L(SC)_detect.emf Shutdown by short circuit current detection Before switching on, the device is measuring the battery voltage Vbb(0). In case Vbb(0) is above Vbb(SCT), the short circuit current threshold IL(SC)high is reduced to a lower level IL(SC)low. Note: In case of a short circuit between OUT and ground, a impedance between Vbat and Vbb pin of the device (see Figure 15) may cause the device’s supply voltage to drop below Vbb(u) before short circuit shutdown threshold is reached. In that case, the device will detect an undervoltage condition and behave as described in Chapter 5.7. 6.2 Short Circuit Impedance The capability to handle single short circuit events depends on the battery voltage as well as on the primary and secondary short impedance. Figure 15 outlines allowable combinations for a single short circuit event of maximum, secondary inductance for given secondary resistance.

To reset a latched protective switch off the fault has to be acknowledged by a falling edge at the DEN pin. For a reset signal it’s recommended to set the DEN signal to HIGH for 20µs before setting DEN to LOW for 20µs. Please refer to Figure for details.

In order to minimize power dissipation, the device offers ReverSaveTM functionality.

It is recommended to use a Z-diode, a varistor (VZa < 42 V) or Vbb clamping power switches with connected loads in parallel. In case of loss of Vbb connection with charged inductive loads, a current path with load current capability has to be provided, to demagnetize the charged inductances. It is recommended to use a diode, a Z-diode or a varistor (VZb < 16 V, VZL+VD < 16 V, ). For higher clamp voltages currents through all pins have to be limited according to the maximum ratings.

Providing a low signal at the DEN pin will disable the reporting. In OFFstate, both, reporting and diagnosis can be disabled by a low signal at DEN pin. The pin IS will be set to tri-state mode when a low signal is provided at the DEN pin. A high signal at the DEN pin enables the reporting and the open load and short to battery diagnosis during OFF mode. A falling edge at the DEN resets a preceding latched output and reporting condition. Please see Figure 20 and Table 1 for details.
