The DRV824x-Q1 and DRV814X-Q1 family of devices has fully integrated H-bridge and Half-Bridge drivers intended for a wide range of automotive applications. The H-Bridge devices can be configured as a single full-bridge driver or as two independent half-bridge drivers. Designed in a BiCMOS high-power process technology node, this monolithic family of devices in a power package offer excellent power handling and thermal capability while providing compact package size, ease of layout, EMI control, accurate current sense, robustness, and diagnostic capability. This family provides an identical pin function with scalable R_ON (current capability) to support different loads.

Transient Current Capability

The DRV824X-Q1 and DRV814x-Q1 families are scalable by current. TI's multiple drivers allow for the scalability to meet needs of your system loads. The following table shows the driver capability over time both with and without switching loss.

The current capability below is based on thermal simulations using a 40mm × 40mm × 1.6mm, 4-layer PCB for 85°C ambient temperature.

Note:

Driver OCP minimum current limit is about 2.5 × I at 0.1s, so OCP is not triggered by capacitive load transients
PWM adds switching losses (depending on VM voltage, PWM frequency, slew rates) that reduce the current capability
Switching losses approximately $V M \times I (l o a d) \times \frac{V M}{S R} \times f (P W M)$
where
1. VM = 13.5V
2. f(PWM) = 20kHz
3. SR = 23V/µsec
