UVLO (Under-voltage lockout protection) preventing deep discharge, protecting the battery.
Features include a floating gate driver designed for bootstrap operation, excellent dv/dt immunity, excellent negative VS transient immunity, a wide VCC range, UVLO on low-side and high-side, Schmitt-trigger input with internal pull-down, output in phase with input, and excellent latch immunity on all inputs & outputs.
com)-- Future Electronics, a global leading distributor of electronic components, offers the HIP2103/04: 60V, 1A/2A Peak, Half Bridge Driver with 4V UVLO from Intersil.

Across the family the driver ICs feature V CC Under Voltage Lock Out (UVLO) while the IRS2005 also includes V BS UVLO, further improving system reliability.
An internal under voltage lockout (UVLO) feature prevents the PE9915x devices from powering up before input voltage rises above the UVLO threshold limit.
In addition, the LT3091 s accurate shutdown thresholds enable a programmable UVLO threshold for either the regulator s input supply or a positive system supply voltage.
Programmable Fault Protection (OVP, OCP, SCP, LOS, UVLO, OVLO, OTP)
UVLO circuits for both channels prevent malfunction when VCC and VBS are lower than the specified threshold voltage.
The device s lower voltage drop at peak currents also provides a larger voltage margin over the UVLO (undervoltage lockout) level, helping prevent undesired undervoltage lockout conditions with the load.
The new oPFC[TM] ICs offer advanced system-enabling and protective features including dedicated pin for over-voltage protection, cycle by cycle peak current limitation, open loop protection, VCC UVLO and programmable soft-start.
