3 Description

TPS4816-Q1 is a family of low IQ smart high side

drivers with protection and diagnostics. With wide

operating voltage range of 3.5V to 95V, (100V

absolute-maximum rating) the device is suitable for

12V, 24V, and 48V automotive system designs.

The device has a strong 0.5A peak source and 2A

peak sink GATE driver that enables power switching

using parallel FETs in high current system designs.

Use INP as the gate driver control input. MOSFET

slew rate control (ON and OFF) is possible by placing

external R-C components.

It also integrates a pre-charge driver (G) with control

input (INP_G). This features enables designs that

must drive large capacitive loads. In shutdown mode,

the controller draws a total shutdown current of 1μA at

48V supply input.

The device has accurate bi-directional current sensing

(±2%) output (IMON, I_DIR) with adjustable I2t based

overcurrent and short circuit protection (±5%) using

an external RSNS resistor and FLT indication. Autoretry

and latch-off fault behavior can be configured.

The device also has NTC based temperature sensing

(TMP) and monitoring output (ITMPO) output for

overtemperature detection of external FETs.

TPS4816-Q1 is available in a 23-pin VQFN package.
