DESCRIPTION The VND05B, VND05B (011Y), VND05B (012Y) is a monolithic device designed in STMicroelectronics VIPower technology, intended for driving resistive or inductive loads with one side connected to ground. This device has two channels, and a common diagnostic. Built-in thermal shutdown protects the chip from overtemperature and short circuit. The status output provides an indication of open load in on state, open load in off state, overtemperature conditions and stuck-on to VCC. BLOCK DIAGRAM

Switching Time Waveforms
FUNCTIONAL DESCRIPTION The device has a common diagnostic output for both channels which indicates open load in onstate, open load in off-state, overtemperature conditions and stuck-on to VCC . From the falling edge of the input signal, the status output, initially low to signal a fault condition (overtemperature or open load on-state), will go back to a high state with a different delay in case of overtemperature (tpovl) and in case of open load (t pol) respectively. This feature allows to discriminate the nature of the detected fault. To protect the device against short-circuit and overcurrent condition, the thermal protection turns the integrated PowerMOS off at a minimum junction temperature of 140C. When this temperature returns to 125C the switch is automatically turned in again. In short-circuit the protection reacts with virtually no delay, the sensor (one for each channel) being located inside each of the two PowerMOS areas. This positioning allows the device to operate with one channel in automatic thermal cycling and the other one on a normal load. An internal function of the devices ensures the fast demagnetization of inductive loads with a typical voltage (Vdemag) of -18V. This function allows to greatly reduce the power dissipation according to the formula: Pdem= 0.5*Lload*(Iload)2*[(VCC+Vdemag)/Vdemag]*f where f= switching frequency and Vdemag = demagnetization voltage.
The maximum inductance which causes the chip temperature to reach the shutdown temperature in a specified thermal environment is a function of the load current for a fixed VCC, Vdemag and f according to the above formula. In this device if the GND pin is disconnected, with VCC not exceeding 16V, both channels will switch off. PROTECTING THE REVERSE BATTERY DEVICE AGAINST
The simplest way to protect the device against a continuous reverse battery voltage (-26V) is to insert a Schottky diode between pin 2 (GND) and ground, as shown in the typical application circuit (fig. 2). The consequences of the voltage drop across this diode are as follows: - If the input is pulled to power GND, a negative voltage of -Vf is seen by the device. (Vil, Vih thresholds and VSTAT are increased by Vf with respect to power GND). - The undervoltage shutdown level is increased by Vf. If there is no need for the control unit to handle external analog signals referred to the power GND, the best approach is to connect the reference potential of the control unit to the device ground (see application circuit in fig. 3), which becomes the common signal GND for the whole control board avoiding shift on Vil, Vih and VSTAT. This solution allows the use of a standard diode.
