Description

The VN5E025AJ-E is a single channel high-side

driver manufactured in the ST proprietary

VIPower M0-5 technology and housed in the tiny

PowerSSO-12 package. The VN5E025AJ-E is

designed to drive 12 V automotive grounded

loads delivering protection, diagnostics and easy

3 V and 5 V CMOS compatible interface with any

microcontroller.

The device integrates advanced protective

functions such as load current limitation, inrush

and overload active management by power

limitation, over-temperature shut-off with auto-

restart and over-voltage active clamp. A dedicated

analog current sense pin is associated with every

output channel in order to provide Ehnanced

diagnostic functions including fast detection of

overload and short-circuit to ground through

power limitation indication, over-temperature

indication, short-circuit to V

diagnosis and ON-

state and OFF-state open load detection.

The current sensing and diagnostic feedback of

the whole device can be disabled by pulling the

CS_DIS pin high to allow sharing of the external

sense resistor with other similar devices

VN5E025AJ-E Application information values. This shift varies depending on how many devices are ON in the case of several high side drivers sharing the same RGND. If the calculated power dissipation requires the use of a large resistor, or several devices have to share the same resistor, then ST suggests using solution 2 below. 3.1.2 Solution 2: diode (DGND) in the ground line Note that a resistor (RGND=1kΩ) should be inserted in parallel to DGND if the device drives an inductive load.

Application information 3.4 VN5E025AJ-E Current sense and diagnostic The current sense pin performs a double function (see Figure 33: Current sense and diagnostic): ● Current mirror of the load current in normal operation, delivering a current proportional to the load one according to a know ratio KX. The current ISENSE can be easily converted to a voltage VSENSE by means of an external resistor RSENSE.

Small or no current is delivered by the current sense during the on state depending on the nature of the short circuit.
